I was going through some rubber molds today to determine what needs to be replaced, I found an unmarked mold of an ejection seat but didn't remember which one it was, until I poured some resin to see what I had in there.
It was the MB mk5 ejection seat I did for the F-8 Crusader. I retired it from Sprue Bros some time ago when others showed up on the market.
However, the casting came out nice so I can pour a few until it mold deteriorates.
If there is any interest, PM me and I will cast one for you...
