Alvin,
Your analysis of the typo in
Luger Story is essentially correct (except that the interval of 6167-6196 is 30 pieces, not 28) and if you have a copy of Jan Still's new "Central Powers Pistols" you will find the identical analysis on page 413.
Currently, at least as of 3 January 2004, serial number 7108 was in the possession of a Mr.Henry Richardson as reported on Jan Still's GunBoards forum on that date, and that is the first time it was noted as having the take down numbered on the left side. Prior to that the change in numbering from the right round to the left flat had only been observed on #7138. The reporting of #7108 dropped the change-over down to within the Bannerman purchase. By the way, that is another typo in
Luger Story, the Luger in the Springfield Arsenal collection is #7018, not #7108, and it is a mismatch having barrel #6196. Isn't it interesting that the barrel number was included in the Bannerman purchase, yet the frame with that barrel was not?!!
