I'll start keeping records of build dates in a spreadsheet. Don't post serial #s. Most important is how hard to break loose vs. loosening vs. build date vs. no issues. So, here's the format:
#1 Build date: ####
#2 Can't loosen breakdown screw: y/n
#3 Loosens after fire (but never #1): y/n
#4 No issues with #2 or #3: y/n
what else?
