What bike is this 'Norton' logo from?

Hi All: When I bought my '74 'Commando' in September, I received with it this cast aluminum 'Norton' plate. It is clearly from a motorcycle, but looks to me to be older than my vintage. The back side has two bolts and what appears to be the remnants of fiberglass--as if the logo was pried off something. The whole thing is quite curved--which the photos hopefully show, but I'm not entirely sure whether that curvature is damage or it was cast that way. I think the latter, considering the ribs on the back side. Can anyone tell me what it's from? .....here's hoping it is something special!

It's cut out of a timing cover.

You're right! So it is! I suspect the previous owner set out to make himself a belt buckle. Here I was hoping that it was from the engine of an original limited production factory racing Manx, or something.

Looks more like its been cast especially for a belt buckle.
And patterned on a timing cover.
The Commando was the only Norton with a big logo like that.

If it was a timing cover, you'd expect to see the fixings for the half time pinion gear shaft.
Or where they'd been ground off (on the back).
Instead, its just sand-casting marks...

Well....finish it! There are guys on this forum who could TIG weld a hook and loop and make a buckle anyone on this forum would envy. Ask for quotes....

Looks suited to be a belt buckle. Would make a nice hitch reciever cover also.

I wonder if that was left over from making a timing cover tool to adjust the chain? I hadn't thought of that, could be done. Cool.

You could weld a loop to the back of it and wear it like the skull ring The Phantom had. When you socked someone they'd become an advertisement for Norton. -Really great publicity !

bwolfe is right. If it was from a homemade intermediate shaft support tool it wouldn't have the boss on the back side. You can see it from the back here:

Definitely looks like a belt buckle to me, too bad it doesn't say "long stroker" underneath the logo. I mean if you're going to brag you might as well advertise too.
