Hi Rob
I am going to guess it would have to be the holes for the side mounted z arm...they are a perfect match to the pattern that was on my other 67 CDN2. This was in service till 1976 until it was disposed of same year.
Since no one did anything to this since it was bought in 1976. I spoke to the original owner he did nothing bought it and let it sit. The sold it to a business who flipped it straight away to a lady who also let it sit in a shed whom I bought it from. I did find a dozen or so spent rounds for that cal gun I found under and next to the fuel tank. Not blanks but spent live round casings.
So any thoughts...?
