I have a later model BRPE18 with a 146677 6-level punch block (with advanced feed hole). I am looking for a 170751 5-level punch block to replace it. I also have an early model BRPE3 with a 124336 5-level block Q: is this compatible with the later BRPE18? A: No. I removed and examined the two.

I will know more about this when I disassemble a 6-level BRPE punch and see what is useful for a 5-level refit. The punch pins and associated solenoids and actuating levers should all be fine - The early style BRPE3 punch block dimensions are definitely different from the new style.
