So, I paged through the bulk of the Brother documentation, and it looks like I have pretty good coverage of Brother models between the late 70’s to the early 90’s, very heavy on the 80’s. Good news for Brother Electric appreciators. This documentation extends up to the WP series word processor line and at least one Brother dot-matrix printer.
Speaking of the printer, the above Service Update was the only page in the whole stack where Brother officially explains their serial number scheme. It describes how to decipher the serial number of a model 2024L Dot Matrix printer, so at first glance it seems irrelevant to typewriters… except…
Yeah, it looks like a match for the scheme they used all the way back since the 1960’s for their manual JP-1 models. Well, that suggests that Brother probably always serial numbers machines this way, and that it can be assumed that daisywheel wedge serial numbers can also be deciphered using the above formula.
Here’s another document that confirms that typewriters still conformed to this formula in 1979. It also incidentally tells us that you got a much better warranty if you bought a Signature from Monkey Wards than you got when buying a Brother.
Sure enough, I checked the one Brother Wedge I do know the serial number and date for and the serial number matches the date the Service and Parts manual was published, and the date I had already figured out from other sources. Then, to the Typewriter Database to check the other two Brother daisywheels that are uploaded there, and they check out against the publication dates of their service manuals too.
UPDATE: Check it out – Brother Sewing Machines also follow this serial numbering scheme.
Brother sewing machine serial numbers are coded to indicate the manufacture date of the machine. The letter and first number indicate the month and last digit of the year the machine was made. Because the first number in the serial number could correspond to a year in any decade, you need help from Brother International Corp., the machine’s manufacturer, to determine when the machine was made. You can submit an email request through the company’s website.
There’s plenty of mystery still in Brother serial numbers. There are examples in the database that have no month code. I hit a few thrifts and saw one Brother wedge, which I took the serial number off, and was surprised to find it had 2 letters in its serial number. *sigh*
In other news, it’s dry season for nicely-priced typewriters in thrifts lately. The only thrift that seems to get typers is the North Goodwill, and ever since they put out that $99 SM-3 I mentioned a few posts ago, they’ve taken to slapping crazy-high prices on any manual typewriter including these:
I didn’t end up empty-handed though. Today I finally found an Aceliner stapler at a thrift ($2). I’ll show that off once I get it cleaned up. It’s a fairly boring grey color, but it has the “Aceliner” embossing on the top, so I’m happy. Besides, it’ll match my grey typewriters.
What else, what else? Oh, yeah – the “Library” is now open at the Typewriter Database for logged-in Typewriter Hunter level members. Enjoy! There’s a few other things you might notice as well, but I forget what all I did over the week.
And here’s a revolving Olivetti for your pleasure. Hopefully Amazon won’t sue me for violating their new patent on taking photographs against a white background:
