Hey Tim, With all this talk about stamping this horn, you do mark your horns somehow, don't you? My understanding has been that HCH requires a trademark and date on all horns by guild members. I put my mark on all my horns with a date and serial number on the bottom at the base plug as small and inconspicuous as I can. These days, I don't fill the mark. So, you have to use magnification in a raking light to see it.
