My 1931 catalogue says ¡°TWO FINDERS are supplied with the 1931 models, the
usual brilliant pattern and a neat direct vision type, fitted to side of camera¡±
(capitals as in the original) so any model prior to this would have only the
brilliant finder.
?
I don¡¯t have a UK catalogue earlier than 1931, but your camera was
certainly available in the US in 1930, and I am sure it would have been readily
available here soon after its introduction; Zeiss Ikon were very active in the
export market.
Many thanks
David, it seems very early indeed, and surprising that it's popped up in the
north of England unless, like my late uncle's Voigtl?nder, it came back with him
when he returned after the war.

I think I have partially
answered my own query by going through some of the groups online files, it
appears serials starting with O or P refer to 1928 but was the lack of the two
frame viewfinder common on these early Ikonta 520/2's.
