I'm looking for the short (1 1/2") actuator (twist on/off) assembly. There are 2 styles...the first had a 3" knurled body and the second has the 1 1/2" knurled body..I prefer with lighthead (mr11, mr16, h1,) and cord..... I don't need the canister, batteries, charger, but will consider if the price is right.....PM me if you have one
