Hi Stefan, I may have some brass for you (but I have to check up in my mountain place - the original owners tried out lots of different arts & crafts but were only really good at drinking whiskey and smoking cigars :doublethumbsup: ... not bad for two old ladies ... but they had lots and lots of "stuff" lying around and I know I have both copper and brass pieces just don't know the thicknesses). Will be up there this Sunday and let you know / if I find anything of interest! I will just send it (no $$ my treat as it lets me get rid of more 'stuff') unless you tell me you don't want it - just PM me if you don't want it ... sorry for not seeing this earlier but wouldn't have been up to the house until now anyway.
Hope all is well!
