You'll notice that the gallery on the TWdB (https://typewriterdatabase.com/Remington.Streamliner.42.bmys) has a number of different prefixes for these models. I've got two that start with "AX" while others are "EX", "FX", "HX", "IX", "MX", and "NX". These different prefixes surely indicate something, but what that is isn't known.

My first guesses are that it may have something to do with the keyboard configuration or number of keys or maybe it's the country of manufacture as Remington went from manufacturing in the US to Canada, Holland, and England all around the time of these machines. it might also be platen width, color, or it maybe something internally like the specific assembly line they rolled off of or incredibly subtle style or manufacturing changes which may relate to spare parts replacements. You can use the examples in the database to try to compare and contrast them to puzzle it out.

Where was yours manufactured? What keyboard does it have?

Be sure to upload your example to the database with the details you do have as more examples make these things easier to puzzle out as time goes by.

Serial Number<br /> Each typewriter carries its own serial number. Lift the cover plate, and looking at the machine from the right side, you will note the serial number stamped directly behind the touch Selector on the left side of the machine. Record this number for use in ordering supplies and accessories or as identification in case of theft.

Typically the SG1 has at least 3 serial numbers. Two matching ones on the main body (one hiding deep inside), and the third on the bottom portion of the carriage, which may or may not match the other two. (The carriages were meant to be easily swappable for machines with the same CPI/escapement sizes.) Removing the carriage will usually reveal the body serial number (typically a 7-XXXXXXXXX) format which you can compare with the grid of serial number ranges to see where yours fits in at https://typewriterdatabase.com/olympia.61.typewriter-serial-number-database.

I just got mine and have finished most of its servicing, though one or two small adjustments remain for it to be where I want it to be. Beyond this, it's been spectacular. See also: https://boffosocko.com/tag/Olympia-sg1/

What is the purpose of a serial number? What does it do for you? There are serial numbers on things all around you; do you know where all of those are? The VIN number on your vehicle maybe?

People now are only using them to approximate manufacturing dates for fun, but they were generally only used by the factory or repair people to identify specific machines and/or tie issues after manufacture back to production line problems. Do they need to be easily accessed or visible for these purposes? The people who really need them generally know exactly where they are and how to find them.

Sometimes they're used to create inventories for owners or in cases of theft, but these generally aren't common uses that need high visibility. Because they can be removed or defaced, should they be put in easily findable and accessible places?

Generally they're stamped in at the factory during production on integral parts of the machine during assembly. As a result, they can often be hidden or covered up by parts (especially exterior panels and body styling) added later. If it's on an exterior, easy-to-remove part, what good is it?

If it helps, here's a diagram of some common locations:

I've been looking at the typewriter database and have been able to discern the fact that the designator YY=88 seems to indicate that an FP had a Royal HH-like palm tabulator, where the serial number is of the form: FP[P,E,S]-XX-YY-#######, where XX is the platen length and YY is for other special features.

I can't help but wonder what the YY = 92 indicates on Martyn's machine.

For a second, I thought perhaps the "88" in the serial number was a designator for the palm tabulator, but one of the other two in the database doesn't have that option (visually), though the single picture (of 5853) looks like it may have broken off or been removed on that example: - https://typewriterdatabase.com/1960-royal-fp.1241.typewriter - https://typewriterdatabase.com/1961-royal-fp.5853.typewriter

If you upload some additional photos of yours to the database, perhaps we can puzzle out what the "88" designator means if it's not the palm tabulator functionality?

The E on FPE means "elite" or 12 characters per inch. The "13" indicates a 13 inch wide platen. The raw serial number seems to indicate it was made in 1960: https://typewriterdatabase.com/royal.72.typewriter-serial-number-database

It's a common misconception that the database lists all serial numbers.

You'll need to identify the make (and preferably the model) to search the database. Then you'll want to look at the serial numbers which your serial number appears between to be able to identify the year (or month if the data is granular enough) your machine was made. Reading the notes at the header of each page will give you details for how best to read and interpret the charts for each manufacturer. Notes and footnotes will provide you with additional details when available.

You can then compare your machine against others which individuals have photographed and uploaded to the database. Feel free to add your typewriter as an example by making an account of your own. Doing this is sure to help researches and other enthusiasts in the future. Don't forget photos of your manual, tools which came with your machine, your case, and original dated purchase receipts if you have them.
