Charles Lancaster trade sourced SLE. Low grade, good quality.

Rib should be marked Charles Lancasters W&R Plain Hammerless Ejector

Id say $1500 to $2200 would be fair.

These guns were no frills, good quality, good bang for your buck kinda things. Sometimes referred to as Colonial grades. Ive even seen some marked with a crown on the lock plates. A very basic, good quality gun that passed on the extra finishing and embellishments and the price reflected that.
