It's a Safari Deluxe.
Looking for a pair of Weaver style bases (the ones with a slot across) suitable to fit on a Parker-Hale.
You want WEAVER Top Mount Bases for FN Mauser. I fitted the same to several Heym SR20N’s. It says on the packaging they fit PH 1000, 1000C, 1100, 1200, and 1700 … so they will fit yours which has 1.410” diameter receiver ring. I’m pretty sure of that. These also fit Winchester M70, Musgrave & other mauser 98-based actions.
The front receiver ring mount is #46 (p/n 48046) & the rear bridge mount (which is deeper) is #45 (p/n 48045). Mine came with 6/14 grub screws of different lengths to match the U.S. style threaded holes drilled fore and aft in ring & bridge.
