HandyDan Posted October 27, 2016 Report Share Posted October 27, 2016 I searched for it under picture framing thinking it might be used for sizing matting but struck out there too.

John Morris Posted October 27, 2016 Author Report Share Posted October 27, 2016 I am kind of stuck on the whole solid brass thing, why is anything solid brass?
