I REALLY don't know about Stens.
One night some time ago, while working on a museum exhibit, I had three frames sitting on the bench at the same time. They were all from different makers and they were all different.
No matter, anyway: NONE of them were like the ones I saw in Denmark, most of which had been turned out in local garages.
BTW, the Long Branch frame was the best-made of the lot. It was black phosphate finished.
