[GreenKeys] Model 26 Update

[Ed Sharpe Archivist for SMECC via GreenKeys]

speaking of  acetic acid... the plastic  window  on  the  26 is it acetate!?
 
there have been a rash of  rotting enigma machines  due to a  green acetate 
filter stored in the top of the enigma cases as an option for the  
machine....  literally has rotted the metal keys of many machines or least  case 
corroded them...\
 
Got the crypto gang   on board  with the test strips   that the  film folk 
use to  test for 'vinegar syndrome' which is  something us archivists  deal  
with  all the   time....

Roy,

Thanks for the info on the rewinder, and the tips for  workign with 
enameled wire.  I will file that for future  reference.

Yes, I do need to secure my coil repair somehow, just not  sure how yet. 
Easiest would be to re-wrap it in something like  friction tape, which 
is very much what was on it originally.  Epoxy  seems too permanent in 
case it needs attention again.  RTV might be  good, but it has the acetic 
acid carrier which is probably not a good  idea.  The original cloth wrap 
is still there, maybe I will just  gently close that up and tack it 
closed with a bit of epoxy or some other  glue.

73,

D.
