Let's go, Canada!!
Today's topic is about an armored vehicle that was developed to provide anti-aircraft protection for allied forces in WWII, but when it came to completion, the allied air superiority was overwhelming. With that, the order for 135 Canadian vehicles and another 130 for the British were cancelled, with the construction of only 3 complete units (in addition to many turrets...). Today we are going to talk about the Skink AA 20mm Quad tank.
 |
| Skink Anti Aircraft 20mm Quad tank |
History:
Tank AA, 20 mm Quad, Skink was a Canadian self-propelled anti-aircraft gun (SPAAG), developed in 1943-44, in response to a requirement from the Canadian Army Overseas. Due to a lack of threat from the German air force, the Skink was cancelled in 1944 , after only 3 were built from Grizzly I cruisers.

The development of a fully enclosed quadruple 20mm mounting on the chassis of the Grizzly tank (Canadian-built M4A1 Sherman tank) was approved by the Canadian Army Technical Development Board as Project 47 in March, 1943.

In keeping with the tradition of giving Canadian armoured fighting vehicles animal names, the proposed tank was named Skink, Ontario’s only native specie of lizard.

The Canadian Ministry of Munitions and Supply had the turret designed in-house by its Army Engineering Design Branch (AEDB) with help from the Inspection Board. The Waterloo Manufacturing Co. in Waterloo, Ontario, was given the task of building a preliminary wooden mock-up. This was completed on 15 September 1943.

The construction of two welded rolled armour pilot turrets was then authorized. The first pilot turret was demonstrated in mid-December. In January 1944 a pilot turret was successfully tested on a Grizzly chassis.

Due to the challenges of welding a turret of such a complex shape from rolled homogeneous armour plate, Dominion Foundries of Hamilton was contracted to produce a fully enclosed cast turret (the largest armour casting ever made in Canada).
 |

Originaly it was planned to arm the Skink with four 20 mm Hispano-Suiza cannons and the first prototypes were so-armed. In January 1944, the 21st Army Group in Europe decided that only British 20mm Polsten guns would be used (the Polsten was a simplified derivative of the Oerlikon cannon) by its units.

This required a redesign of the turret, which was completed in April. This change delayed the project by 3 to 4 months, while 21 Army Group's reduction in the number of AA guns to be issued to its units led to a reduction in the number of Skink turrets which were required. This dwindled to zero in late July 1944, when 21 Army Group decided that as the German air force - the Luftwaffe - had been virtually eliminated over North West Europe, there was no longer a requirement for anti-aircraft tanks. The Skink contract was cancelled in mid-August and only three complete vehicles and eight turret kits were completed.

The Skink’s four 20mm Polsten guns could fire 650 rounds per minute per gun. A modified oilgear hydraulic traverse with two pumps could rotate the turret at up to 65 degress per second and - crucially for a quick response - accelerate from rest to 60 degrees in 2 seconds.
The guns elevation was also hydraulically assisted so the guns could move at up to 45 degress per second in an arc from -5 to +80. The gunner controlled both elevation and rotation with a joystick, and used a Mk.IX reflector sight. Initially it had been planned to build 300 Skink turrets for the Canadian and British armies.

In action:
Some sources claim that 2, or perhaps all 3 Skinks were sent to England for evaluation and that at least one, or perhaps two, were sent to Europe with the First Canadian Army for combat testing, in early 1945.

At that time, the task of refitting and replacing vehicles for the front line was in charge of the 25th Armored Delivery Regiment - "The Elgin Regiment", whose responsibility was to ensure that replacement and reinforcement vehicles could be constantly fed to front-line units, to compensate for mechanical or combat losses.

After being transhipped to Antwerp on 24 January 1945, it reached the Canadian forces a few miles surroundings of Nijmegen, Holland, on 4 February, and entered combat in support of the 6th Canadian Armoured Regiment (1st Hussards) at north of Nijmegen bridge. In this action, the Skink saw combat, in the ground support role, during the Allied push into Germany, working with two Shermans and an Infantry platoon, in the second wave infantry mopping up role with devestating effect. In this action, the Skink firing several bursts into a building occupied by about 50 German's, 10 of whom were wounded by 20mm HEI-T fragments and the remainder quickly surrendered.

Thanks to colleagues Paul Roberts and Rick Cooper for helping with the historical research on the Skinks' operational actions at the end of WWII.
 |
| Thanks, Lads!! |
All units found it to be a valuable asset. However no enemy aircraft presented itself to the Skink's guns and its main function was to flush out stubborn pockets of enemy infantry and force their surrender.
The remaining Skink pilots and the completed turrets went into long-term storage in Canada where, at some point, they were scrapped. Only some unfinished turret castings salvaged from the firing range survive.

The kit:
Existed on the market a conversion resin kit for the low bustle Skink, by (today extinct) Panzer Resin Models. And at that time I received the commission to make the master for the "high bustle" turret version... Today, these kit (with upgrades) is currently available from the Bold Division.

I had already built the low bustle version, for my collection. So Fabio de Melo (the owner of Panzer Resin Models) commissioned me to master the high bustle version of this turret.

And since I love scratch things, let's get to work!! I received some low bustle turrets and a hull to serve as a template for the works...

Now, it´s primer time:

But here we have a big problem: at the time of the construction of this kit (2000), there were no Canadian Dry Pin tracks in 1/35 scale on the market. And, in the real Skinks photos, the version with VVSS "American Sherman" tracks (and drive sprocket) was the low bustle, as in the photo below :
 |

The "high bustle" version shows the CDP (Canadian Dry Pin) tracks.
 |
| Notice the high bustle turret and the CDP tracks. |
Today, there are CDP tracks from Panda Plastics and Friulmodels ....I chose the metal ones to correct my old kit. But first, I had to disassemble my tank, yanking the old vinyl Italeri tracks and drive wheels...That's easy to say now, but it's still very exciting...
 |
| The correct tracks: Canadian Dry pin tracks, from Friulmodels. |
 |
| Tracks in place...Wow...Notice the space for spare tracks in the turret right side view |
