Calvin- one trick I use on my gunners workbench- I have several small horseshoe magnets- as all the metal parts of Parkers are made of ferrous metals of various grades- they will all stick to a magnet-hopefully preventing their loss- Austin knows those older lifters, as he does other types of Parkers over the years- I'll pass on the lifters, as I have no experience (yet) with them--But slow and steady, carefully fitted screwdrivers, plenty of lighting on your work area are all helpful-- good luck!!
