Is there a serial number registry out there or is someone keeping track of them?  We have serial number 6D13

Thanks but it doesn't show how many are actually still out there.

6D1 - 125. 125 possible ones. It is already in a class of not many or possibly the last one left

I have 6D-7. Got it back after being gone for 4 years. Serial # 1is at a museum in Montana (I believe) and it’s getting a total rebuild. He says they have 2 others. Not sure if they are #7’s or not. I’ve seen multiple others over the years including # 47. Wish I would have written the #’s down that I’ve seen.

There is a great SE# book for Graders at the ACMOC Store. $20 and well worth the money!!

We have 6D1 at the Historical Museum at Fort Missoula, (Montana Historic Equipment Area). It's 3/4 the way through a total restoration. We also have 6D35, running, but left in its work clothes. We also have a 9, (8A363), running, but left in its work clothes.

We just finished a frame up restoration of a 1918 Holt 75.

If you're ever in Missoula, Swing by. We run the steam powered sawmill on the last Saturday in April and 4th of July.
