Anyway, as stated, that was not my main reason for going through the archive. Instead it was Jacques mentioning of another rare(ish?) T-62: "I also have pics of a m62 that was modded to add a AAMG...how many others were like this....??" (I also remember the thread you and Mr. Gary Denozo had on M-L a while back on the topic)
I remembered two of the photos that Mike P posted here some time ago.


Note the weld seam running along the MG 'cupola'. Jacques, is this what you refered to in your statement? Interestingly enough the Chadian 62 have the same weld seam:

So, the bottom line: what's the storry on that weld seam? Just one of the model 1972 batches or modded model 1962's? AFAIK the 'cupola' are usually casted togheter with the turret (no weld seam).
Fire away...
