Forgive me if you already know this but Dr. Dimock of Buffalo also produced Tally-Ho Bitters
which was put up in a bottle of similar shape and colour to the Tamarac Bitters.
Ring & Ham is catalogue the Tally-Ho Bitters as D76 and rate it as rare.
Ferdinand Meyer has provided some background information on Dr. Dimock on his Peachridge Glass site which is linked below.
NO, Did not know anything about the Tally Ho, I was looking for that Peachridge Glass site but forget the name & couldn't find it but thats where I got info on some other Bitters bottles before. Anyways, Thanks for the link & the Info. LEON.
