[GreenKeys] Re: TP 173979 Print Hammer Head

[gil smith]

Hi Don:

I have quite a few typing reperfs around, but have never worked on one.

On two 35s, I cannot really see into the area where the hammer is located.

On two 28s, I can see the notched lever arm as show in your diagram, but 
there are no hammers.

On another 28 typing reperf, it looks like a there is not supposed to be a 
hammer, since the lever arm is flat and horizontal (not vertical like the 
others).  Were there some reperfs that used just a flat metal arm to strike 
the ribbon?

Then I have this other 28 reperf, a brand-new still-on-plywood unit that I 
got from Jay Waller, may he rest in peace.  This unit looks to have the 
hammer.  However, I do not know how to disassemble this unit.  What's involved?

thanks,

gil
