Most Greeer people can tell the difference between a G gun and a FP pretty quickly and from a distance. The actions, while somewhat similar, have different shapes and the barrel lumps are very different.
If the price is right on the FH70, and you dont want to have the ejectors repaired (due to cost, etc), take the springs out and make it an extractor gun. Shouldnt jack with the action functioning correctly at all.
Top tang safeties on FP, Gs and even Ds are pretty rare in the Greener world. Usually a very special order item.
I did notice that the forward part of the receiver had a pronounced roundness and slimmer than the rear portion--- presumably a feature of the Princeps.
Some idiot welded a piece on the safety to get a little more leverage. Yuk!!!
The gun is nicely housed in the case with the French type fitting. Uncommon on an English gun but have seen Scottish guns so fitted.
This gun needs refurbishing by a dedicated collector.
