PB; The Trunk Shoppe purchased the one piece brass tacks from a manufacturer in Colorado. When I find my stash of brass tacks I think I'll come up with the address as I have purchased one piece brass tacks from the Colorado foundry. You may find their location on internet faster than I can locate my tack stash. The last time I talked to the The Trunk Shoppe person (Area local Parson) he told me he was going to reduce his time reproducing period trunks. One reason for the decision was material was costing to much. The tacks are very-very costly. AJ
