[GreenKeys] M28 Reperf printing hammers...

[Don Robert House K9TTY]

A great idea… The first thing that comes to mind is availability.
Not sure how many of these are still available.

There are a lot of the original and updated perforator hammer heads in an envelope in my parts locker.
Sadly like all of the 200 pounds of parts are still locked up in San Diego.

Perhaps someday I can manage to get that parts cabinet back…
