[GreenKeys] The Iron Horse - GPE - 5 Unit Perforator (Bell 14A)

[DR HOUSE]

Greenkeyers,

I scanned and edited three Teletype Bulletins, 167, 1039, and 1012.
This completely covers the so-called GPE or Green and Black Perforators.
1931 to 1954... Figure 20 is the schematic.

I have two versions, both 81 pages long.  Hi-Res is 18 MegaBytes
the Lo-Res is 2.5 MegaBytes.  The Hi-Res is pretty much unnecessary.

Let me know off list if you would like a PDF. Alternatively I can  
print and
send you a paper copy (the 18 MB) for $9.95 including Media Mail  
postage.

Happy teletyping,
Don
