Help with Record 71

[Zeddedhed]

I've just recently dusted down my Record 71 from the top shelf and had a go with it - works beautifully (and why wouldn't it) but the fence screw and washer are missing.

I have no knowledge of threads and the associated voodoo that some of you engineering/toolmaking types do.

Could someone tell what the thread size is supposed to be and where I might find a suitable replacement with it's washer (I'm sure any old washer will probably do but I'm probably wrong)

I just checked on my Stanley and it's 3/16" Whitworth (24 tpi).
I'm 90% sure that the Record will be the same.
I have a suitable screw and washer to spare so drop me a pm with your address if you want them.

Andy, that's extremely kind of you. Thank you indeed.
PM on the way.
