This is I.R. #7, Lowenstein, with rose pink facings and brass buttons.
After I had finished painting all four units, and had flocked the bases, I bumped the tray they were resting on, and they all showered down onto the concrete floor of the basement below!
Many were knocked off their bases, bayonets were bent, and these particular sculpts by Lucas have separate heads, so a half dozen or so were decapitated. Ugh!
Fortunately, crawling around on the floor for a while lead to finding all the missing heads, the bayonets were largely successfully straightened, and the heads restored to the appropriate bodies. Note to self; do NOT do THAT again!
