I was able to take this one a bit further, with the holidays near, I want to bring it to the paint-ready stage...
I bent some clamps for the bridge and cut the individual planks from balsa. With this kind of scratch-project, I sometimes feel I'm shooting myself in the foot for all this ambition 🙂
So it happens you need to make an initial move, look at it critically and then - when not satisfied with the result - figure out the mistakes made and do it all over agan. This model may not be larger than 15x15cm but it is very technically demanding...
So it happened I had bent the underside of one of the pontoons about 2mm off. That was too much for symmetry. As a consequence, I had to take my scalpel and remove part of it again. Now it looks on for my standards and the two pontoons are almost identical.
Symmetry in this model is important because the absence of it will immediately show on a model this small.
Having said that, I have this funny feeling that the German kitmaker Das Werk will actually make a model of this some time. They had it on the box-art of a recent Dragon Sd. Kfz. 7 re-box:
There appear to be resin kits in the market, but this attempt is more fun (also the parts are more crisp than when made in a 10 y/o resin mold).
Hope you like it, happy modeling, Michel.
