It was only due to chance comparing different thick R3s that I discovered a core with the same front but where 2 different back dies were used ! Something in theory that might exist and had not found until now !
Only recently I had started to include closeups of the reverse core in comparisons .
As a few weeks back the existance of 2 cores was brought up and shown here I then did not pay much attention to the reverse side .
I have done up a chart showing all 3 very destinct reverse core dies .... to which I can only identify 2 front dies . At the same time I noticed a difference in the frame beading appearance .
In the montage I gave my thoughts about this ,.... In the chart I used numbers for reference only and they have no other meaning . There are not that many around ... so members I would ask those who have one to have a look .
Interesting to see if we realy only have 2 front core dies or 3 ??? And additionaly how many front and reverse core die combinations we might come up with !!
Note this is for the thick version only ... I have not looked at the thin version... does something simular exist ???
