I'm thinking these are from before 1920, maybe a lot before, as they don't have any Britains branding that I can see. If you have information on these fellows and are of a mind to share, I'd enjoy hearing from you!
Either way, they're very nice and quite rare. I haven't been able to find many comparables to use for pricing. In the meantime, if you have a realistic offer, please let me know.
