Can't find info about these Motorola transistors

[jnd]

About year ago I was buying a lot of old transistors, mainly Tesla. Now I was going through them, sorting and measuring some. I focused on the TRnn series which I have more types than it seemed before.

They are various types, all are low power, small or larger metal can. Most of them have Motorola logo and if the number below type is date, some of them are from 1972. I tried several times at Google but can't find any info about them but surely there must be some catalog which lists them. I'll be happy if anyone can show me more data than I found with measuring them with simple semiconductor tester.

I have the following:

TR04 PNP Ge
TR05 NPN Si
TR16 NPN Si
TR17 NPN Si
TR26 NPN Si
TR31 PNP Si

Besides Motorola ones I have also from few other manufacturers. Tesla made five TRnn types, I probably have at least one of each but some doesn't have Tesla marking. The rest are various from TI, ITT and Sescosem if I matched their logos right. I can make photos later if you want.

Type in your Transistor Numbers and you get Information + Datasheet

i think the TR ......is just from the word transistor....
so......i think its just numbered.....tr...01-02-03-05-07-16 ect....

no any luck to find something.... imo...
