There's even a fiddle bed version.
That article is also wrong though too, in that it says (under the 1934 improved Model 15 section) that the model 15 got reverse in the 50s. I have 2 model 15s that have reverse, and neither is as new as that. My oldest one is a 1936, so reverse is as least as old as that.
Bah. Well, at least my letter's more accurate than their information! Didn't most of the 15 clones come about in the 40's? I was taking a stab at when the highest density of the machines started to show up.
