ID a BBC timing chain

[Ryan]

Doing some research on some second hand part on the 454. Cant find any info on this timing chain.
7-96 123BA-B. Either of the (B)s could be (R)s. It was stamped at an angle and the bottom of the letters are hard to see. It has a circle, square and Triangle. Not sure what those are for.

The circle, square and triangle might be used to set the cam timing. Straight up , advanced, and retarded. I'm guessing the 7-96 is a manufacture date. The others might be a part number, plant number, shift number, or something totally different.

why are you trying to identify it? if it's got slop, just get a different timing set..

sounds like one of probably a hundred different timing sets for big blocks that have multiple keyways for setting cam timing..
