The lower hull is almost done on my KV-3:
Needless to say, thinks didn't go exactly to the article in the conversion book. If you decide to tackle this yourself, the instructions for cutting the side applies
only to the right side. Once you've cut them as instructed, use the lengths to cut the left side. I did not, unfortunately, and now this has cost me three kits instead of two

(guess I'll have to turn the leftovers into a blowed-up KV-2 diorama later...)
Also, I had to move several of the rubber arm-stops - not an easy task. Replacement arm-stop mounts had to be scribed out of the remainder side pieces, sanded to the appropriate width, etc. And, unfortunately, I didn't catch one as being off until I took the photos this AM

(first photo, fifth from front).
But, progress is being made, despite my best efforts...
