Old Germany - Various Questions

IIRC, they're at the end of the GDR section.




I'm assuming because Berlin was technically under Allied occupation until reunification in 1990. But who knows with Scott – their Germany listings are a mess.




Michel takes a mixed approach with the perfs. It simply notes "various perforations" under the general listings, but then has sections with more detailed information. Here are the more detailed notes. In Michel the compound perfs are given as width:height.

Thank you for your great replies.

About the "how to measure" - if I have a perf gauge that moves in discrete steps of 1/2 or 1/4, I have two options: Tooth to groove and tooth to tooth, like this:


I find the TTT (Tooth To Thooth) less accurate with worn teeth.

As for how to interpret the measurement, I tried this: I used the "Tooth to Groove" measurement, aligning the tooth on the right side and watching the discrepancies on the left side.
I concluded that it was slightly less than 11 but clearly higher than 10 1/2, placing it between 10 3/4 and 11. Do you agree?

Yes. If rounded to halves, it, probably, is listed as 11. If rounded to quarters it might be 10 3/4 or 11.
