Does anyone have a photo of a D7-6T that you could share?. They were built by American Car and Foundry in the 1945 time period and only about 1000 were built. I understand they have a 6 roller frame rather than the 5 roller frame common to other D7's.
I searched for D7-6T in the forum but did not see any photos and those that owned one are gone from the forum. The D7 Book by David Doyle does not have a photo of the 6T either.

Any help is appreciated and thanks.

If you go back to page 3 there is a whole thread on ACF built D7s with pictures and video.

Thanks, do you have the title of the thread? I only saw the 4T version and not the 6T in the ACF thread.

Hi, D4Jim.
After trawling through my library, I have found just two photos allegedly showing 6T D7s.

Thanks Deas,
The top photo of the Military version might be a 6T but I cannot see the track rollers for a count or the side of the seat for the ACF logo. It sure might be.
The second "old yeller" photo does not show the ACF logo on the side of the seat so doubt it is a 6T or 4T. Rock guards make it impossible to tell. The ACF logo should be just below the umbrella bracket on the tank if it was made by ACF. Could not see it after blowing up the photo.
First Pic is sure better than anything I had. Thanks.

Thanks Josh and Deas,
Two revelations about the 6T. The video does not show an ACF logo on the machine although the logo was on the 4T series. It appears the track frame contains only 5 rollers, not 6 as stated in David Doyle's book about the D7. (from the other photos) Supposedly that was a way to tell the 4T from the 6T as the 6T had an additional roller but that appears to be bogus..
Thanks again for the help, much appreciated.
If anyone can put an eyeball on a verified 6T it would be interesting to count the rollers for verification.

I think this is a D7-6T made by ACF under the Trackson T7 stuff, it’s a runner in the UK. No expert though so if anyone has any other ideas let me know. I’m wondering if all T7s were ACF as they needed the longer track frames..

I thought I had seen the ACF stamp on that machine. Interesting.
