Hi Mick,
Many moons ago I built the Verlinden 1/35th scale deep wading sherman, so I guestimated the dimensions from that kit and various images from the internet including P.E kit plans for the 1/35th scale example.
I'm used to be able to just buying resin Conversion sets for my 1/35 builds so this my largest scratch built converted project so far. I'm hoping once into paint she'll look something like these.
Matt
