Sorry for the long silence, but I had other business to attend to, we do have a job after all don't we
Thanks Jim for your fine words.... "esoteric", tsk
But you are right, there is little written on this topic. Unfortunately I just have Lhoste/Buigne to get information from. They have "Talabot freres" listed, where the freres is also written with a capital "F" and smaller "res". Does anyone have a chance to check the other "big books" on markings?
Perhaps there is a solution to this riddle after all.
All the best
