We have a discussion on the danish vintageure forum - a member has bought a correctly looking Heuer Bundeswehr, but it has no flyback - and no hack setting.
No on some URLs you can read that it was made with Valjoux 23, (some even mention 22) and 222 and 230 - the two later being fly back movement, but I do not think 22 and 23 would be fly back - they would then be 222 or 230 in fact.

As I wrote, you can read that the Bundeswehr was made with 22 and or 23 but I have never come across an example.

To me it sounds a bit strange that the Bundeswehr would accept a non flyback version, as late as around 1967 where a flyback version should be available.

QUESTION - Has anyone SEEN an example with 22 or 23 non flybackback movement in Heuer Bundeswehr, and if so, which you do you think they used those movement in?

Best regards
