What is the item?
Difficult to point to a particular candidate without that info.
If this happened, then the original order from Holmegaard, would have been dealt with by Glassexport/Skloexport and not directly by any factory.
I know of a number of non-typical Sklo Union items, produced for the Scandinavian market. What is interesting is that in nearly every case, the designer is unrecorded, whereas the designs from (and designers working for) Glassexport/Skloexport are documented.
