Holt 75 and 45 identification help required

Here are some Holt 75 and 45 pics from the BSOT that I have been scratching my head over. Any information on owners and/or serial numbers would be very welcome!

Many thanks

David

Tom, just a few quick questions:

(1) The BSOT listing mentions Jack Alexander's 75, serial no. 3776 - was this one not actually there, or is this the one in my 5th pic? I also have Jack Wallace listed as the owner of the restored green Peoria-built Holt.

(2) The listing gives the serial no. of Doug Peltzer's Holt as 102175, which is too many digits. Do you know what the correct no. is? I'm not even sure whether this tractor was there either.

Many thanks

David
