My free opinion.

It does not have any value as a collectable to those who collect MS rifles. It is a shooter

.243 is not a rare chambering.

Full stock rifles and double triggers bring a premium over half stock rifles

Drilled and tapped rifles are not looked upon with favor.

1956 models (concave cheek rest) are not a lot of folks favorite.

Reblue is a negative.

I would ask $1000.00 for it from your description and hope for the best. Be prepared to take less! $800.00ish. Gunbroker is another world as far as pricing goes. That may be your best bet for $$$

Faith and love of others knows no mileage nor bounds. That's simply the way it is.
