Check HiCampy's site. He has some good details about dust caps.
Thank! that is interesting. Getting closer haha. It looks like he almost identifies them...........but he doesnt really haha
They are later Record pedals, post toe strap loop which these do not have. Most likely from a later middle 70's Raleigh International. For whatever reason, Raleigh had Campagnolo stamp a model number into the top of the alloy. Way back in the day assembling these bikes we noticed the stamping, that was particular to Raleigh, at least for all the pedals we went through from various distributors.

If you used a good laminated leather toe strap you would not need two straps per pedal.
