HI
I don't have a picture handy but one maker using the rooster and or cockerel was Gebruder Weyersburg. A page I came across mentions his marks
http://ww2.rediscov.com/spring/VFPCG...TABASE=objects,
midtenrelics.com has an 1840/1822 type sabre with the mark and it is those that I have seen the mark on before.
What do these other blades look like? I have no isea of the longevity of the marks and whether Weyersburg might have continued using it for some blades such as those headed for South and Central American countries.
Cheers
GC
