Were not allowed to use those on gas pipe here in Canada....But I can get them for 15 cents (without the "W")
On a concourse restoration on a big block vette... they actually look for that stuff along with proper date codes...paint/chalk markes etc... Madness I say!!!
:16suspect just imagine if somebody bought a bunch of these back when they were cheap! it would've been an awesome investment
Ok, so you go down to the local hardware store, buy a handful of them at 15 cents a pop, along with a W punch. Go home, punch the W in all of them, sandblast them and sell them for $85?
