Help me identify a gearbox

[heraldcoupe]

I'm just getting to the end of clearing my old storage barn. There are a few pieces I'm getting rid of via ebay rather than moving, including an A-type gearbox with damaged bellhousing.
Being more familiar with the components of the small chassis Triumphs, I've struggled to find an identification number on this gearbox. There are various casting numbers which I know are unlikely to be helpful, but there must be a serial number stamped somewhere?



The overdrive serial is easy enough:



Any help appreciated,

Cheers,
Bill.

A=type big saloon box. number is usually stamped on the bump in the bellhousing where the starter motor bendix goes.

Yup, Big T  A type OD box.

Thanks guys. I was pretty sure it was big Saloon, but as it came with a job lot I didn't want to assume anything.
I've just been back up to the barn and there's not a hint of a number anywhere.

Cheers,
Bill.

Don't have the A type MOD box for my Mk1 saloon that I thought was agreed so PM sent.

Hello Bill,

the number should be stamped adjacent to where the clutch arm comes out of the bellhousing.
