1915 Corona 3 Serial # 67730 1915 Corona 3 typewriter, Serial # 67730 Fumitaka Hayashi's 1915 Corona 3 typewriter. 2026-08-21 From the Virtual Typewriter Collection of Fumitaka Hayashi: 1915 Corona 3 Serial # 67730 An eraly Corona 3.

I've wanted one of these, as they seem to be a reasonably obtainable early successful portable typewriter. I broke my rule about not buying portables without cases for this example.

It arrived with the carriage off. It was missing the bearings and bearing holder. I replaced the bearings (standard 3/16" bearing) and I fashioned a holder with some wire. Then I discovered that the loose dog was likely chipped. There's no escapement wheel on these, just the loose and rigid dogs engaging on a rack on the carriage. Looking into service manuals, this particular model seems to have an earlier escapement design, as most examples have an escapement with the spring running vertically, rather than horizontally parallel to the platen. Sooo, that means it would likely be quite difficult to source the part from a parts machine.

It's a real shame, as otherwise this example of Corona 3 is in rather good condition. The decals are intact, the paint is not too bad, and surprisingly the platen rubber is pretty good, as are the feet. The platen feeds the paper rather nicely.

As the escapement is non-functional, I had to manually move the carriage to obtain a limited typing sample. Typeface is some sort of Elite.

It's a perfectly fine display piece, just missing a half-millimeter of metal off the loose dog preventing proper functioning.

Messing with it showed me the rather elegant, simple design of the Corona 3.

Another Goodwill acquisition. This was sent from Ventura/Santa Barbara, California.

Having the typebar up engages the rigid dog, so that the carriage stays put. The loose dog is broken.

Ignore the wire, it is there to stop the carriage from going all the way to the left, as the escapement is broken.

A shot of the escapement. This arrangement with the spring running along the carriage is different than what's on most service manuals, that have a different arrangement with the spring running vertically. Underneath the middle there are the loose and rigid dogs. The loose dog on this is about a millimeter short, and it looks like it had broken off.

It folds! It only folds to get a bit shorter to fit into a smaller case. I guess it also makes service somewhat easier.

Trying very hard to be more judicious in my acquisitions...

I like interesting typefaces. I like tinkering with my acquisitions to make them work.


RESEARCH NOTE: When researching the Corona 3 on a computer with lots of screen real estate, you may find that launching the Corona Serial Number page and the Corona 3 By Model/Year/Serial page in new browser windows can give you interesting perspectives on changes throughout the model series.
