Go to Sears, they sell Ingersol Rand. See if the can order the parts, or get ahold of a IR dealer. If not then...take the two apart and make one good air gun

yeah i have no idea what model they are, they are old..... and combining the 2 wont work, one is a 3/8" and one is a 1/2"

i'll try sears...... as far as an IR dealer, we dont have those hear, or none that will cater to an individual like me.... you walk in there, and htey all sya its commercial accounts only
