This model is based on Philips model 205U [Holz], just like NSF model Aristona H128U.

There is also a Siera model S108U reported in a bakelite case, however it is unlikely that this ever existed. The booklet "Siera memento of tubes and models 1932-1946" only mentions the wooden model with a UY21 rectifier.
