Library search on marks leads to possible piece that is a copy, concern is the number of marks but most is that of my reverse L design. My L’s seem to have closed “o” on the top two extensions, unlike any of the Various forms in the research book. It is blue , V in the center, a gold mark off left and a gray mark off the top of the L’s, and 4 marks within the L’s 6 area’s of the > > V < < ^ angles. The first angle has what seems to be a small capitol T and larger capitol D: clockwise up is marked within by a quote mark; top angle has two dots and the fourth upper right has a < and small 7 1 with the lower and the botom angles blank. Hope you can picture it as the pictures I can get wouldn't help much but can be sent direct and a sketch picture. Thanks for help.
