[GreenKeys] Model 28 parts

[vineguy423 at gmail.com]

Hi all
  New to the list and not sure of the protocol. Ex Coast guard ET from the early model 40 days but dad was career Air Force tech/ government employee (37 years). Dad passed on Veterans Day and I'm trying to help mom sort through his "accumulations".  So far I've come across a complete  model 28 print head, several rolls of vintage yellow paper, what looks to be several sets of alignment tools, manuals and bag after bag of NOS parts all bagged with there part number cards with military stock numbers including gears, felts, rollers metal parts....etc. enough spares to keep someone running for decades it seems.  
  Is this of any value or is it give away stuff. I've set it all aside for my next trip ...just unloaded his tube collection after I inventoried several boxes  except for a few larger specimens anyway, I would appreciate any feedback. Stellar job with this mailing list I've enjoyed following the threads. 

Thanks
Doug
