Gerald, We at the SV are in need of a supplier for Lukenheimer pops, and parts. Also looking for railroad pop offs, as the style we have been using aren't really right, in that the more they pop off, the less accurate they are. Contact me back channel if you would please. Looks like things are moving forward at CATS, that is good. When we fired the 19 last weekend, the (newly calibrated pop off, blew at 169, and then didn't re-seat, we dropped the fire at 140 lbs. and slugged water to it, never did seat. this hurt, as we had school specials every day this week, and it will be Thursday before we get a replacement pop. anyway, thanks Gerald, and keep on the great work.
