Hi Woodcutter
if my thinking is correct and it's an original NPSM it should have 540 pto at 1500 rpm marked on the rev counter if it's got the original clock fitted still. the SM would be 540, at 1200 rpm and be marked for raised pto unit at 1600 rpm.
If you got a SM already go look at the pto drive casting under the gearbox. The rounded flange/bulge with the drain plug in should be about 3/4" deep all round it's half moon shape. on a NPSM that flange is about 1 3/4 -2" deep at a guess. The NPSM had a bigger gear in the bottom so the casting was altered to suit that larger gear. i checked my 62 and 64 again today for the difference in size and it's right. Mine are semi berried in snow, so couldn't get under to read the casting numbers on that pto drive, But I do know they have different part no's. We had this discussion here a few years ago and I checked that then for the guy.
I hope that may help you as well, The hyd top or that top link bracket or even the head could have been swapped, It's not uncommon, in the fordson world.
I saw a super major tractor on ebay was supposed to be the best restored out there, the price said it was anyway

. it wasn't even close to accurate with how much of it wasn't super major, it never got a bid or re appeared after either

. if we had a picture of it here, there would of been a prize for the person spotting the most inaccuracy's

.
I guess as you already got a Heinz 58th variety, I can see why you want to be careful now, if you think it's a real mutt casting codes tell a story as well.
Good luck and keep us updated
