A friend recently received this among spares for a job he is working on:

Nice early 30's 10 stud block.
Ideal for my 10 stud crankcase, if it's surplus Tony, since I don't have a block!

Additional thoughts:
No webbing or extended flange
Knock in core plugs not screw in. 
Either or both of these would be on a factory casting.

Is it repro?
Hutchings or elsewhere?

charles.

it looks to be a 9 stud block.

previous user has only used 8 studs?

so are the 8 in standard position. were as they are usually moved around to get 10 studs in.

although there are 4 studs on the valve chest so an unconvensional 10 stud.

the valve chest is very crudly cast, and the seats for the barrel nuts havent been back cut. so id suggest its not made by austin. 

a more modern manufacturer.

Doh! - I hadn't spotted that. Bizarre

I wonder what it was for.

And the valve chest stud is over the oil pump ?

[Tony Betts]

well spotted tony, that could be fun.

it looks like they may have had extra studs over the cam, now half holes.

and tony g, could you tell me if those core plugs can be removed or are they a machined surface. they look rather perfect.

thanks tony.

Tony.

I know no more than the photographs show .

Could it be Reliant  or American ?

I think Bantam Tony. I have an engine here and the crankcase is completely different, as well as being reversed. I was told it came over here from America during the war to run a generator.

Hi Russell

Does the Bantam crankcase have the  10 block studs ?

It's a 1937 - 1941 American Bantam
