Several years ago I thought I would try to make my own gas checks, and got into a group buy for copper sheets... well I still have the copper!
I do not remember what gauge I ordered but just measured it and it appears to be .010". There are nine 8" x 11" sheets ... 2 1/2 lbs of copper.
All proceed will go to Cast Boolits -- I am footing the postage, so please be generous and remember that this site is funded by people like you and me.
Highest bid by 8:00 pm 3/9 gets it.
