Strombergshyttan - Asta Stromberg or Gunnar Nylund?

B925, B912 and B927. Models released about 1960 (not earlier I think).If these are models by Gunnar Nylund, the drawings must have been lying at least 3-4 years after he stopped working for Strombergshyttan. But my theory is that they are Asta Stromberg compositions, maybe inspired by Nylund at least in terms of model B927.

What I can see now, Nylund was not working for Strombergshyttan 1957-1966. Models released 1957 and 1958 can be by Nylund. After that, some models probably are of his basic design, and modified to new models by Asta Stromberg. And some models are of her own basic design. She seems to have been very active in designing from the late 1950s. Before I say more specifically what I think, I must look into the catalogs from 1955, 1958 and 1960, which I will soon have access to. But as I said, my theory for now is that Asta Stromberg stands behind the vases, with or without inspiration from Gunnar Nylund.

The copper toned underlay I don't know the color code for. It must be a special color, not occuring in the catalogs I have access to for now. The most common colors are X70 ametist, X73 golden-yellow, X74 green, X75 sargasso-green, X76 smoke-grey and X77 brown.

I have another model with this copper toned underlay, B894. This is for sure a basic design by Gunnar Nylund (B679), from his most active time in Strombergshyttan 1955-56. The model B894 from 1958-59, I think is a slightly modifyed version with thicker walls and thicker bottom. In any case you can often see B894 with quite thick bottom. I have one with very thick bottom, and the miniatyre of the model has allways thicker bottom what I know.
