Semi-Useless Facts.....
The model 15 could be found with upper case J as an apostrophe on US
machines.
Upper case J on a foreign 15 is a BELL Code.
Upper case H on a civilian15 is a "#".
Upper case H on a fully configured military machine and some civilian
machines was a motor shutoff code.
The model 26 was never really suitable for press service because the R
and Y were next to each other. The standard reversal test "RYRYRY"
would see the type wheel print one of these (I forget which) correctly,
and when the other character was sent the type wheel would have to make
a complete rotation plus one more rotary increment for the other. If the
felt clutch which drove the type wheel shaft was not in perfect
adjustment a string of RYs would not look so good.
If the felt clutch was adjusted with more tension on the clutch to
assure a proper string of RYs, it was very likely that the type wheel
stop arm would have more force than necessary, and the end would then
break off, causing the type wheel to spin endlessly.
The model 26 had a paper feed arrangement that was really crummy.
Model 26's seldom had a "BLANK" keylever.
The model 26 was only equipped with a Holding Magnet selector, while
14's and 15's were equipped with either, depending on what point in
history they were made.
The Canadians had model 14's and 15's with TEMPEST magnetic shielding
over the selector magnets, and that feature only on Holding Magnet
selectors.
And now you know...
