I have a 4 digit SN model 21 extractor gun that is missing the forend wood. The gun is a little rough so as long as it is serviceable it may work. Please PM me with what you have and price.
I Replied to your post a few hours ago but it must not have gone through.
Anyway, I sold some M21 fore end wood on ebay several months ago. It was marked “16510” and “16”.
Please send me a PM if you would like more info, pictures, buyer’s address, etc.
And by the way, I don’t think you can make it fit on a Parker! (Just kidding, LOL, or something like that.)
