ID this spine car set

I'm thinking MTH. I have the K-line set, they come in a square box - the trucks on the K-line are from old style freight cars (bettendorf) instead of roller bearing type.

Here's K-line, Trailer is Bowser/Weaver 53'

It looks like a mix and match of stacks from 20-95036 spine set with a couple of 48's (SF,UP) substituted for the NS and BN trailers.  Was there an ISO Tank- Santa Fe to the right of the CSX (outside the photo right edge)?  The two 20' CSX & ISO SF were end spines on the 20-95036.

Plus the BN 48' may have come from the 20-95035 spine set

how you can tell MTH vs. K-line:

K-line:

Earlier Symington Wayne plastic trucks or later die cast bettendorf trucks

Movable 5th wheel trailer hitch

Metal grab rails

metal brake wheel and stantions

MTH:

Plastic bodies

NON moavable hitch [either raised or lowered]

only 2 sets made - both do NOT have the air hose detail on coupler trucks

correct die cast roller bearing sprung trucks

came with BOth containers and 48' Trailers

They weren't marked as production samples, but I think this might be what they are. If not, then it seems like some sort of hodge podge set.
Anyone have any ideas?

Sounds like a hodge podge set becasue production would have TTAX markings on them
