I noticed the flipper plungers in my Stern Magic are a little different to the 'usual' plunger, in that they are machined with a "fat" end of the plunger, and the remainder of the plunger is a bit thinner.

Is there anything particularly special about this arrangement? Do they perform any different to a generic plunger?

The ones installed seem OK (other than the grease/oil on them  ) but was wondering if I ever had to replace them would I need to find the same odd plungers, hit generics with a lathe or just replace them with generics?

Cheers

Perfect timing Jacob !

I've been working out a "rebuild kit" for early Stern machines, and the ONLY part that has been a problem is the plunger and the coil stop. All other parts are available from PBR.

The plunger is part number - A-1972 (no longer available)
The coil stop is part number - A-186 (available from Marco Spec)

These are the other parts required if you wanted a "full rebuild" (From Steve at PBR)
