M29 Weasel video, variants?

[cluttonfred]

I came across this neat OSS briefing film referenced in the Wikipedia article on the M29 Weasel.

The 10 minute video--worth the wait, I promise--includes some discussion of the various alternative approaches to travel across ice and snow that were evaluated as well as a lot of footage of the vehicle in action. I think I want one for Christmas!

Does anyone know of any prototype or proposed variants of the weasel, perhaps armed versions? The video mentions use as a prime mover...maybe towing a mortar or pack howitzer on skis?

The Australian Antarctic Division used Weasels extensively in Antarctica until the 1960s. Their variants had hard shelters on top of them. Perhaps if you did a search for them?

Here a paper about the Weasel written in 1945:

You can read it online (or download every single page). Not sure it contains details about variants, I did not read it (it is not in my favourites list), but at least there is a sketch of the 8-rollers prototype.
