Doing that type of work to that forend would not be too difficult. It does look as if the forend might be a bit shorter than it should be. But the perspective in that picture is a bit deceptive. It looks like it might have more of the shape and length of a Trojan forend. The short length might make it a little difficult to get the right shape to the wood leading down to an added metal forend tip.

I'm hard pressed to believe that's a Fajen stock. If it is, it's the best fit I have ever seen. If you're planning on keeping the gun, who cares; it's a nice stock. If it were my gun, I would have a Dog's head butt plate put on, which is more in keeping with a VHE 20ga.
I do have a fore end tip around here somewhere, but it's from a higher grade gun, and probably B or A.

A DHBP would look great, but since its already wearing a recoil pad that looks to be about an inch thick, I'm assuming that a DHBP would leave it with too short of a length of pull. I agree, if that's a Fajen buttstock, its the best one I've ever seen.

Thank you all for the great input. I have been asked to sell this and several other guns by a deceased friend's wife. Therefore I will not be making any modifications to any of the guns. They were all used for quail hunting in middle Ga & South Texas. There was only this one Parker and it appears he had the gun fitted to him. Some of the other guns also appear to have had stock work done. Mostly to lengthen the pull as he was a tall man.

Late Rem Parker ( this is one of the last Parkers) forends were broader and flatter than earlier Parker forends and to the end of production, original Parker forends for graded guns had tips.

Fajen Gunstocks of Warsaw, Missouri made Parker stocks that were machine inletted and for extra cost, could be checkered by them. The stocks could be ordered in various grades of black walnut from local trees. Guns could be sent to the Fajen custom shop for hand fitting. Donnie Gemmes was the last production manager for Fajen and other fine stockists worked there. The issue was time and money. We very often see D grade guns here without drop points, too thick wrist and butt and with steeply angled thumb grooves, a dead telltale for Fajen standard replacement stocks.

For those who care about Parker authenticity, a replacement stock that is not true to Parker form will significantly degrade value. We have consistantly seen that value in Parkers is directly related to authenticity.
