Wargame pieces from late 1970's and early 1980's

These are a sample of what we were using as wargame pieces in the late 1970's and early 1980's. They were reduced to 1/16in = 1 foot scale and colored with colored pencils. Now, they could be colorized digitally. They need to be cleaned up, but it seemed like they might prove useful to someone. There are more, including higher-quality drawings done in ink at 1/48 scale.

This is the link to the complete sheet that had these as a small part.
