Transmission numbers, Old / Newer 901's Options

[Randal]

I know the first number below is a later model mag case 901.

The number is 914.301.301.03.

Also have a case with 914.301.302.00 on the back.

Anyone know the nomenclature of the numbers?

Randal,

That page has info on "type" and "serial" numbers. It also has some example photos of some of the different stamping combos. I am guessing you are having a hard time reading what is stamped on the bottom. A combination of grease and/or the fact it's on the bottom and in a place that can get scraped up a bit makes them hard to read.

As it stands right now, the info you give doesn't really 100% match up to what I would expect it to be, but it's close. My best guess (assuming you are miss reading some characters/numbers) at this point is that it started it's life as a 914/11 1972. Might it be 914/11 HA0048078? As you can see from the photos on that page, they really were all of the place as to how they stamped them. Sometimes it is type and serial, sometimes it's just the serial and then later on the "serial" number was really day of manufacture, so assuming they made more than one a day (!) you would have multiple with the same value stamped on them.

You didn't say if it was a tail or side. The 914/11 is a tail shift, but either way, it could have started life as a tail and then converted to side. And as always if someone has done work to it, who knows what gears are inside at this point.
