Ticking Sound at Idle on 120 Straight 8

This may be a wild goose chase, and hardly ranks with some of the issues dealt with in this forum. But here goes...

I have noticed a light mechanical ticking sound in the engine of my 1941 120 Club Coupe. Not very loud, but there from start up (cold) and perhaps a bit less as it warms up. Engine was rebuilt a while back. Tappet clearances and compression checked more recently (all ok). Oil pressure steady at 40psi. It runs fine, and I probably would not notice it except that these engines are so quiet!

Any idea what this might be? One suggestion is that it's the drive finger on the mechanical fuel pump. Could be.

Any other ideas? Has anybody else noticed the same thing? Not sure if I should even worry about it.

Cheers

Brian
