I finished up this tank destroyer brigade for a friend's Hammer's Slammer's game at Celesticon, coming up October 24th weekend. The brigade is built from the wonderful Old Crow 15mm models, with some customization, conversions and details added (see my workbench pictures, below). The Zaporoskiye Brigade is a mercenary unit David Drake's "Hammer's Slammer's" novels, of which I am a huge fan. The paint scheme is a total homage to Mr. Kevin Dallimore's 28mm versions. If you are going plagiarize, might as well do it from one of the best! http://www.kevindallimore.co.uk/HEAVY%20TANKS/index.html
The decals, stowage/detail bits and tank commanders are Flames of War. Up gunned barrels on the tanks are brass/copper/styrene mix.
This whole project from cleaning to varnishing took about 10 hours, as they needed to be on table for play-testing on time. I am pretty pleased with the results.
