Hi all,
I found a Tekno Auto-transporter in Denmark in good condition at 85 Euro incl. ramp. I think that is a nice price. Now we can compare the two.
At first sight both the trailer and the ramp look exactly the same but it turns out that the trailer castings are completely different. The Dinky trailer is furthermore 5 mm longer than the Tekno. Both are made up by two pieces: The Dinky has an 'inside' casting and an 'outside' casting. The Tekno has a separate top casting (the light grey part).
The ramps have the same measurements but have a slight diffrent construction. You can see that the sheet metal is folded inside on the Tekno version:
The 'flaps' don't have exactly the same design but very little differ:
Since we havn't seen a picture of any real Pullmore I would say that Tekno was inspired by the Dinky version, but they developed their own construction.
