Hi

Does anyone happen to know what size bolts are used to hold the Spring/Graphic back onto a Anniversary Speed Graphic please?

They're obviously not metric, I'm guessing they are some sort of American size/thread?

I don't need the length (that's easy!) - I'm going to buy longer ones anyway as I want to design some system that will take the Polaroid 405 back.

Thanks in advance,

James

according to the service manual,

its a 4-40 right hand thread.

You're in luck, then. That's a standard size that you should be able to find in a hardware store (I think you call them something else in the UK, but I can't recall). Failing that, if you have a model railway shop near you, they might have it in stock, although that size is getting a bit large for model work.

OTOH, if the UK has gone entirely metric in everything, you may be out of luck.

Thanks for the info chaps, very helpful indeed, regards, James
