As regards IDF Shermans, M-51, carried the 105mm D-1000 and had modified T-23 turrets. Most were converted from M-4A1 and A3, some with VVSS, some with HVSS, mixed with a big assortment of A4s and A2s. Any Sherman carrying the 75mm 75-50 gun was an M-50, irespective of the chassis. All M-50 and M-51s had the large turret counterweight overhang. Standard, unmodified M-4A3 & M-4A1s 76mm were designated M-1s and were referred to as Super Shermans, (not the M-50 or M-51s) and remained unmodified except for some stowage items.

I have converted two Mato Shermans to IDF and they run pretty well out of the box. Tracks and suspension are nice, but if you want optimum performance, a swap to HL electronics is a good idea. If you want to convert to Israeli Sherman, that turret counterweight is a chore as is the extended mantlet. I did two with sheet styrene and one with resin..IMHO styrene is easier and a lot less messy. My M-51 was made from an older Tammy Sherman. I used aluminum 17 pounder gun tubes for the 75-50 guns and a Pershing gun tube for the M-51. The huge 105mm muzzle brake must be scratch built, but the 17 pounder gun muzzle brake can be Dremeled and modified with no problem. Dave did an absolutely superb job on his M-51 The markings came from a tank in a private collection.
