Home Forums Hunting & Shooting Gunsmithing Remington X-Mark triggers?

A guy brought me four Remington 700 rifles and a sack of new Timney triggers the other day and asked me to install the Timneys. Now, what do I do with the like new X-Marks? Three of them have the adjustment screw on the trigger and the other (older?) one doesn't.
Two of the rifles were unfired and the others looked almost unused--definitely not messed with!
I would like to know if there is a market for them and what they might be worth.

Thanks for your input,
Ken
