The Compur shutters made by the German company F. Deckel, based in München are a good avenue to date of cameras. The number can generally be found on the side rim of the shutter, between advance lever and release switch. Deckel never published production lists. However, as most cameras also carry body and lens serial numbers in addition, collectors have used correlations and other information to compile below lists. An early list has been published in a little french collector's booklet[1] and also appeared in other generally reliable publications [2]. This old assignment is shown in column 2 of below table. However, this older list did not address the introduction of the Compur-Rapid shutter in 1934, which obviously started fresh with 5,xxx,xxx serial numbers, while at the same time the older Compur shutter kept using the old consecutive numbering. In addition, this older list seem to underestimate the Compur production during the late 1920'ies. Therefore, recently (2020) two new lists have been proposed based on >50 examples from different collections[3] (column 3 and 4). On this web-site the author also have programmed a little camera dating tool based on a series of serial number lists [4].
