It may be a Meffert, but I really don't trust the name on the top of the rib to have any part in the construction of the drilling. Instead the initials on the underside of the longarm reveal the craftsmen and may point back to the name atop the rib. Yours may very well fall in the Meffert serial number range but they were sourced for the trade. One thing though: Meffert's philosophy was that he could produce say 10 unadorned longarms in the time it took to make 1 or 2 embelished ones. So it is possible that it was sourced from Meffert but the work order was above what Meffert typical produced. And that was the thread for which I was looking.

In the scheme of things I know very little but am attempting to assemble, or compose, source material. Many have come before me and have laid the ground-work for info that needs to be carried forward. I'm going to hold you to an earthy smoke as well as a lively libation.

Kind Regards,
