Marlin/Glenfield 75 front sight set screw?

[Schlegel]

I am putting the rifle my dad gave me about 80-82 or so back in working order for the first time in 30 years and the front sight set screw has gone missing. Does anyone know where to find one or what size marlin used for set screws generally back then?

Danke!

Thanks guys, that got it. Found a headless set screw off a junked random part, 0.25 inch long, sits just a smidge proud. From the specs the 0.310 headed screw look like it would indeed have worked if I had had to order it.
All together now, scrubbed of rust and grime, stock resealed.
Now if only the ranges were open.
