Thun Chainring Bolts

Major Malfunction

Retro Newbie
Newbie here! I'm currently restoring an 80's Raleigh Record Sprint, unfortunately one of the chainring bolts for the original Thun crankset is missing. I can't find any online, anyone got an idea where I can buy some replacements or would be easier just to bodge something together?? I'll let the picture below do the talking, but the thread is about 6mm. Thanks in advance!



 
Thun chainring bolts, Campagnolo derailleur pivot too!

I apologise for bumping and jumping on your bandwagon but I have an identical problem but five times worse. I have the identical Thun "gold" forged crankset with no bolts at all. It is for a Raleigh Record Sprint that I am putting together from a box. I've got everything there except these crank bolts and spacers and I am also missing the pivot bolt for a Campagnolo 980 rear derailleur that should go on it.
Thank you in advance for any info etc.
 
Re:

Sorry for hijacking this old thread. I need exactly the same screws for my Raleigh Record Sprint. Just wondered if the OP managed to source any or something similar to do the job?
 
I found some at my LBS. They seem to be in the big assortment boxes that decent workshops hold. Failing that, try phoning Bicycle World on 01202 590414, which is where I got them from.
