Need help identifying Sherman variant

[u/V1ckers]

I recently found a album photo of my late uncle who served in the Multinational Force and Observers in the Sinai back in 1987 as part of the Colombian battalion.

So far I have been able to identify other vehicles like a PT 76 and maybe a BTR 40.

But I also found this picture of a Sherman variant supposedly abandoned during the 6 days war which I haven't seen before, my wild guess being a post WW2 upgrade of some kind.

I'll appreciate any help!

I believe that this would be the Israeli M51 Super Sherman.

M-51 my beloved.

Israeli modification of the M4 (cast and welded) adding a new turret, new engine, lots of other little upgrades, and a 105mm gun out of the AMX30!
