Mystery Crank

[vping]

I posted this over in the Pub and someone suggested this crank might be a Triumph. Any clues you guys?

Well, it's not from a TRactor motor...here's the one from my TR3.

Someone over on the other forum mentioned it was from a 1296 big bearing engine.

Looks similar.

I think we have a winner. Thanks RL looks exactly like it. Maybe at one point my friend had an RB Midget for parts or something. Is there any value to it at all? Ebayable that is?

Nice polishing job on the mystery crank.

Wish mine looked that nice. The MGB Crank I just got looks like that though.

It is either a 1500 or 1300 crank. if you measure the distance between the center of the main bearing to the crank bearing, we can tell exactly which type. but at least from the proportions, it looks like the 1300 in my shed. Also what is the diameter of the main / crank bearings?

I was going to suggest it goes to a boat.

Fits up at the front and is connected with a chain.
