Anyone know what this Holley tach drive distributor fits

I found this tach drive distributor and have no idea what it fits? Any gurus out there know?

If you click on the picture it blows up big enough to read the umbers. I tried doing a Google search, but "Holley Distributor" just shows me countless places where to buy Holley parts

And no, its not going on FeePay, I dont deal there anymore May end up here, may end up in s****, depending on answers

 

How many lobes on the point cam? It looks like one from industrial engines from the 50s. I have one here from a Continental 6 cylinder that looks similar.

 

8 cylinder.

 

might be for an industrial motor.....

 

Well, it MIGHT BE for a Henway, as well. Im kinda trying to find out what it IS for

 

have you tried contacting Holly or looking for an industrial catalog? the tach drive might also be for an hour meter instead

might try to see if these guys have a listing:
