[GreenKeys] tape printer survey

[jhhaynes at earthlink.net]

The patent date on the Model 14 is 1930 (patent # 1,745,633 to
Morton & Krum) so it was patented after the M-K merger.  However
the filing date on the patent is the end of 1924 which puts it
closer to the time of the merger.  It's interesting that Sterling
Morton, who became president of Morkrum in 1917,  was both a good
business man and a good machine designer - Howard Krum says so in
his circa 1925 history.

The 5-A ticker - that is a Western Union model number, not a Teletype
number, as Teletype apparently didn't give a model number to the
stock ticker.  It is a 6-level machine and prints on wide tape.  I
don't know how wide, but it prints letters and figures in separate
rows, like the older tickers.  The 401-A, again a W.U. number, is a
Baudot machine printing on 5/16" gummed tape.  I don't know if Teletype
manufactured these or if W.U. had them made; and I don't know if they
are newly made or if they were made from recycled stock tickers.
I owned one once, but it got away from me.
