Yes, would have to be J or K. Still going through my hundreds of pics of sems... Any one have ribbed SWF sem with a J or K letter for the month?

Ok, scratch that theory, I am going through all of my sem pics and have found an "LD" that I restored years ago. So what is the missing letter???

Ok, so here is a question regarding SWF date codes. Among many ribbed SWF sems I have, I have an "IB" and an "MB". Despite the first page of this thread stating that "I" was not used (for year anyway), "I" is the month on my "IB" and it is Sept 1950. What is "MB", or what letter between I and M is skipped because if none were skipped then "M" is the 13th month of the year.

Sorry if this was covered previously in this thread, I didn't read all the posts.

I propose that "M" is December and "L" was skipped because it looks too much like an "I". Just a theory.....

Yes, it is January 1943.

Without checking I cannot say for sure but I am pretty certain the KdF-Wagen Type 60 uses the 90W generator and this is a regulator for it, correct for the KdF Type 60 1943-1944.

Worth it´s weight in gold maybe?

The 90W generator was used again in 1946-47 in the Type 11 Beetle and this regulator would work for on one too but the cover would have been with the cross pressing already.

The date code is on the other side above the Bosch logo, usually very hard to read. As I recall early Kübelwagens had a 90W generator but utilized a different style relay. From 1943 it looked liked this but generator was 130W, also for Schwimmwagen and KdF Type 92/82E. It may be that the KdF-Wagen Type 60 utilized the 90W generator and this relay? Check the date code on it.


You are right mate!
Some brushing and there it was. 1Y

That´s january 1943?
Would be good to know if that type was on a car.

If you have a working 6V generator, you can make a test circuit and turn the generator for example by drill machine. I test my generators and regulators that way.

OK, so not for a car for sure with 90 Watt?
Is there a way to check if it works?

It's a wartime 90W regulator with the interference protection. 1Z on that place doens't mean date code. Could be from a stationary engine when has 90W. "N" could be the correct date code, maybe it's "Z"?

On page 1 there is a set of pics and the question on the Z date code on a D shaped voltage regulator. The Z denotes 1944 a nice'n oldie The pre war date coding for Bosch started in 1920 at A. The post war date coding coincidently started at 1945 with A again.

11N = Nov 1957
10M = Oct 1956

Date codes (if any) for Bosch lenses are cast into the lip at 12 o'clock, under the rubber gasket, and consist of a Roman numeral (for quarter) and letter (for year).

october 52, from the conversion to 160 it seems it has been remanufactured later with parts from a 36hp generator?

Does anyone happen to know what date codes were used on SWF parts (wiper motors) after 1968. I have wiper motors with date codes of 2F 54 and was wondering what year it was made. I know it was made in the '70's or '80's.
