I'd do $150.00 for it ...the scope mount is $40.00ish...and parts are only going to get harder to find...It's a MK1, which is better then a MK1/2 or 2 ...because of the side button for the bolt release...not like the notch rail on a LE Mk2 or 2/3 etc.., that will sometime get chipped...making it hard to close the bolt quickly for a follow up shot...It looks like it was a Parker Hale..or a factory sporter at one time...with the two screw front sight base(holes drilled..looks like) and if the barrel is good..? Is it a 2 or 5 groove barrel? It a Surrey barrel...so could be a 5 groove. I have one, shoots great. And if your looking for a project...it would be great in , 444 marlin...45 acp (for a light shooter).
Keep it or pedal it...It's a LE that has not been bubba too bad yet!
Cheers
