Raimey,
I agree with your premise that the Lindner production was not consistent year to year, and likely nothing close to it. Looking at other period makers (with known production numbers) the yearly production volumes are often very lumpy, to use a technical term.
Changing demand due to the economic health of the market country, internal organizational and marketing changes within the company, etc., etc., would obviously all have an impact on production volumes. Lacking any of that information - and being too lazy to construct some model to account for some of the known issues - I have just assumed consistent production volumes between known "anchor points".
I also look forward to someone one day uncovering the Lindner production records so we can put this all to bed once and for all.
Regards,
Ken
