I've often wondered why a maker wouldn't put their "brand" on an instrument—cost of the equipment perhaps? The maker's mark is of use for an owner in the case where they are selling it on. An unscrupulous, or ignorant, seller might misrepresent the maker.Steve
I think I can probably assemble a barrage of excuses, all of which have a small ring of truth....
"The maker's mark is just a conceit." To paraphrase Burns: "The name is but the guinea's stamp, The flute's the gold for a' that".
"I had too much else on at the time." I think this one is closer to the truth. My early days (going back as far as 1974 when I conceived the notion, and 1975 when I made my first flute) were a whirlwind of discovery, carried out in splendid isolation. So many different flutes to try, so many different approaches to try, so many problems in the originals to overcome, getting them right seemed much more important than bothering with a name stamp.
"Will I be making enough flutes to warrant getting a stamp made?" Always the question, and impossible to answer! I still struggle with it. A few days back I had to order more tuning slides. Given I am now 73 years of age, how many should I order in this batch? And finding out that the chap who makes them is now 86, how many more should I order? Why is this crystal ball not working again?
"How to do it well?". I had seen so many badly stamped flutes that this was a real issue. Stamps where only one end of the name comes out clearly. Stamps that run at a quite jaunty angle to the body, or that suddenly bend upwards or downwards halfway through. Or where the second line is not parallel with the first line, such as in this fake "Rudail and Rose" here in my possession:

Looking back, I'm glad my customer demanded the mark, and I've occasionally been able to add my mark to earlier flutes that came in for recorking tenons, or other maintenance. So, I come down on the side of both marks and serial numbers.
