Anyone have a clue what model Pitless this might be?

I'm trying to determine the type of pitless adapter this might be before pulling.

I could only get a top down image with an infrared camera and the whole Black part of the pulling pipe area that goes into the curvature is throwing me off.

Well is Circa 1997

Well after some exhaustive detective work and some imaging with an old cellphone camera taped to a PVC 1/2" pipe. I've found out this is a Martinson M-B10 Pitless Adapter. Martinson was acquired by Campbell Manufacturing

Looks like a slide type pitless. I would just give it a pull.

Thanks Cary - fortunately my nephew's well company shop has one with the leather o-ring. So we can pull this old corroded side and put the clean replacement in place. And hope the leather o-ring stays intact.

That's the plan

BTW - my nephew is just a young pup in the industry and just said first time he's seen a pitless with leather o-rings. Now I want to see if he's seen a homemade flow inducer that I've put on my pump.

Just to followup for others on this pitless. We pulled this weekend and the old M-B10 had a rubber o-ring circa 1997 installed and not the specified leather L-1.

We installed the clean one my nephew had from his well companies shelf (with it's leather o-ring). All was well on first seating in the casing side - no leaks.

I made some photos of the old M-B10 with it's rubber o-ring to compare to a new Buna 1 3/8 X 1 3/4 X 3/16 (first photo). Also pulled the old o-ring and installed the new one and it fit very well. Slightly smaller than groove so it was stretched slightly when installed.

I believe this o-ring would have worked very well had we needed to use it.
