Remington typewriter serial number dating
A complete rundown of the changes can be found on Richard Polt's in-depth overview of this model.
Not quite a Portable #1 and not quite a Portable #2, the Compact was a model for the European market.
Over half a million were made, making the #1 a fairly easy model for the beginning typewriter collector to find, and in my opinion no collection should be without this milestone in typewriter history.
During its first year of production, The #1 was made in limited quantities, and had to be special-ordered; it could not be purchased from a typewriter dealer until October, 1921.
Most notable of these is the placement of the ribbon spools the carriage in a vertical side-by-side configuration.
Note the single left-hand shift and crinkle paint, typical of this variation.
For lack of a better identifier, I'm calling this intermediate model the 1.5 so as not to confuse it with the Remington-labeled Sholes & Glidden.
As you can see, the sides have been opened, yet the keylevers are covered.
Though the carriage and keyboard are the same as its predecessor, the frame has been lowered and elongated.
This model was a dratmatic departure from the No.1.
The advantage of this is that the carriage is incredibly easy to remove, requiring the removal of only two screws. Loosely similar in design to the No.2 and virtually identical to the No.3 save for a shorter carriage. This #7 was probably intended for the domestic German-speaking market.
