Hey, just saw this, I'll try to remember to look tomorrow to see if I have any extras. (I know I at least have a couple barrels mostly used, a couple that have sharper edges, but I don't want to be left with a barrel of 19 chips.)
I checked my racks, and I didn't find more than just 1 full barrel (I think I may have sold some other barrels over the last couple years), and I don't want to break those up. Sorry.
