I was under the impression that Canadian Armoured Snowmobile Mk Is were converted into Penguin Mk Is. If this was the case, not all of the Armoured Snowmobiles were converted at the same time as here is an image from Exercise Musk Ox showing both vehicles in use.
I have both the Penguin Mk II and Mk III recorded as having been manufactured by Canadian Arsenals Limited. I do not have production figures but again my records indicate that both vehicles had an ambulance version.
Here is an image of a Penguin Mk II.
