Hi Tanque
It will be 1/16 Im afraid. I have no room for 1:10 anymore.

The tracks according to my guesstimates are about Pz III width.

I have two options.

1. Use a Sherman sprocket and tracks. The advantages are that the sprocket is about right size and the tracks are double horned as apparently were those on the M-05. The disadvantages are that the sprocket is a little weird and would require a fair bit of modification and the tracks are and always will be blatantly obviously sherman tracks.

2. Use Pz III tracks and sprocket. Advantages are that tracks look more like the ones in the photo and the sprocket is easier to modify. The big downside is the single guide horn which means the rpad wheels would need a groove in them. If a narrow groove was put in, it might not be that noticeable.

The outside contender is to use a couple of #25 roller chains and appropriate sprocket but fitting guide teeth would be insurmountable for me.

Tiger I transport tracks have been suggested but the sprocket is way too big and the price is more than my entire tank collection is worth I reckon (exagerating a bit there). Other tracks, like the panther ones are just way too wide. Maybe for 1:10 they would work but Im not going down that road just to accomodate some tracks. I really dont have the room.
So to my mind its either Sherman or Pz III tracks. I havent decided yet as Im still thinking about it. But Pz III might be easiest. I have noticed now - I am not familiar with US tanks at all - that the Sherman sprocket engages the track on the very outside of the lonks and that might not look so good at all.

Irrespective of what I choose, its going to be a bodge job with the tracks but thats life I guess.

Any opinion on the matter would be welcome!
