Does anyone know of any data on stem band construction? For instance, this question should be the easiest to answer of mine. When did manufacturers change from copper stem bands to brass? Assuming that would be the same time frame as when copper tacks were changed to brass as well. How about when copper stem bands were first available on the market? I am working on a older Gerrish currently that has iron stem bands and it got me thinking about these. Obviously the date of manufacture predates copper stem bands. E.M. White made his own bands. Was that because when he started building commercial stem bands were not available? When stem bands were made commercially available, did they have alternative uses or were they made for the canoe market? The earliest had flat blacks as far as I know. I am undecided if I want to have new iron bands made for the old Gerrish. Pro's and cons to both sides!
