An easy and fast way to get a look at some Parker Guns that were restored by Babe or Larry is by doing an internet search. As others have posted, correct spelling of their name is a plus, even though a number of vendors who advertise their restored guns fail to do so as well. A couple of examples to try:
DelGrego restored Parker.
Del Grego restored Parker.
Keep in mind earlier restorations will have a cyanide-type color casing. More recent guns done by Larry were color cased by Turnbull Restorations.
Hope this helps.
