SPF I have a air feed that replaces the manual handle lube feed on a Star sizer. It is very similar to the one Magma sells except the air cylinder is shorter and has a shorter throw. So it can't get to the bottom of the lube reservoir to use all the lube before refilling. But other than that it works the same. I got it as a spare for my other cylinder but in 12 years my other has given me perfect service, so this is just sitting in a drawer. 60.00 shipped to your door in CONUS. Please post "I'll take it" here to avoid confusion.
