Yes, if T. Jimenez wouldn't have the scanner for negatives, they would know who has.
My family still has a good bundle of full length movies our grand father made in 40's, 50's and 60's, traveling North Africa with his... 1948 Nash Ambassador! Yep, he'd take that rig down to Southern France, had it hived onto a boat and would do his "Safari" in it, get back the same way and have the body fixed up again! Different times, different customs. But even back then, I doubt that was "normal".
Anyways, the OP's thread, re-awoke my desire to look into the issue of having these films scanned.
If I find something significant... I'll let you know.
... J-D.
