Thanks for the info! Also interestingly, the pop rivet only goes through the hole on the right hand piece, not the left hand piece!?
I have the TR2, TR3 & TR3A, 1953 to 1961 Original Technical Publications CD. Is there a picture anywhere in there? I have the wide rims. Perhaps they were cannibalized from a "donor" TR, hence the Bondo?
Here are three pictures of a rim. One full, one detail where the nock and two holes, and one that shows an outward dimple 180 degrees from the nock.
Are these the right rims for the three piece kit?
