Yelmer, Thanks. I am going to pull the booster this week. Will check for a date code, and post pictures if I find anything. Thanks again Frank

Yes, there is a 66 cast in, and some faint”clocks” which probably indicate month/day. Need to find a source or someone who knows about the Bendix manufacturing process to confirm..

I pulled the Booster today. I am providing pics of the front and back. I have only found 2870 stamped into the booster adjacent to one of the M/C mounting studs. Should there be additional stampings? One thing I did notice was each shell has an "X" Scribed in at the the 12 o'clock or top. Leads me to believe that the booster was rebuilt sometime earlier. That is consistent with the history I know. The longtime previous 2nd owner was a mechanic and probably serviced the part himself vs just replacing. Also included pics of the booster mounted on the Kent Moore Tools the dealers would have used to service the booster in their service dept. These are shown in the shop manual.
