Should I be able to find a part number on this?

Thanks

NO but that appears to be an original, got a pic from the bottom & a pic of the head of one of the studs

No stamped numbers in the metal, just an ink stamped number after the black paint.

paint stamped numbers on assembly line parts? or just over-the-counter parts?

Over the counter for sure, assembly line, not so sure.

Underside

Stud

real deal. you can get a replacement L-bracket from Frank Badelson

That's a 1970 base.
Sometime in 71 they changed to the smaller head, longer stud with no letters for assembly line.
Same part number for both baseplates.
Over the counter bases had the later stud.

Thanks everyone!

Terry - Here's an NOS base that I bought years ago. I would assume an over-the-counter part (based on the lack of the L-shaped brackets).

close up of the stud head

Close-up of the bridge. I seem to remember there are some variations with the bridge, but I can't recall if that was for original parts, or original vs. repro, or maybe that was with the 4-bbl bases...

You are correct Bruce.
I should have stated the majority of the over counter bases were of the later design and lack the feet brackets.
I have a production print somewhere that shows the foot bracket deletion date and a separate part number created for the bracket.
I believe the bridge remained the same, but the very last produced 6 pack shaker bases had a minor trim at the front lip as the dies had become quite troublesome.
I'll see if can find a picture

How do I get in contact with Frank Badelson For L brackets?

I got this off the a quick internet search. Hope its what you need.
