What are these markings..?

[Butch Cassidy]

I have called S&S ... BDM... looked at many pics as I could and yet, no answer. I do know what the SA means: Special Application (it is easy to find on a search) but nothing on the BSA, or the 82 on the bottom of the jugs..... I have a 107" Any ideas.?

82 could be the volume of the compression chamber.

..yea, I was thinking something like that too .... but I see no such markings on any other 107" or any S&S motor...... :/

Regarding the BSA stamp. The first let "B" represents the oil pump machining holes. B stands for 92 and later oil pumps, an A would have stood for 91 and under.

No clue with the SA after it stands for though.

Thank you. And then the SA of the BSA probably means it is a SA crankcase (Special Application) like as noted on the other side. But, the mystery of the 82 remains.
Anyone else have markings like this..?
