[GreenKeys] 33 Print Hammers

[Richard M. Gillingham]

Towards the end of the '28 era in the FAA (Late 1980's!) we got some 
'aftermarket' type hammers from I dunno where.  They were of inferior 
quality, and would either chip or mushroom the business end of the 
hammer in a relatively short time.  I suppose there may be some of these 
still out there, so inspection is in order if you've replaced one 
recently.  

We maintained at least one '28 at the now closed Homestead AFB BASOPS. 
 One day a female Basops worker called to tell us that the "pecker" on 
the typing unit was broken..    Hmmmm....   Hope this one makes it 
through the filters..   ;->

>and spring were separate pieces.
>The palstic/rubber hammers in the 28 reperfs is another story.
>Unfortunately, they were also not made to last forever like the 33 type
