Plus Model has announced an upcoming 1/35 wherry.

Although not an armour piece, it surely will look nice on a diorama.

I am no expert but it seems to me generic enough to fit different eras and world zones, it may be fine either at Dunkirk 1940 or Vietnam 1965.

It is not common to have such equipment at 1/35, and will save a lot of work to those who needed one and had to scratchbuild it
