Alex Martin has Brand Value level three (BV3). Original Quality grade should be grade five or six (most likely - BLE, I assume); OQ5 or OQ6. Current Condition level could be CC2, CC3, or CC4, based on your description. "95%" implies a CC2 (slight use) but the coin finished receiver sounds more like a reblacked gun which is more likely CC4 (heavy use, but no abuse - not a lot of BLE's of this time frame were actually coin finished - look at the action flats for traces of case color to confirm if the action was really coin or colored. BV3-OQ5-CC2 = $4208, BV#-OQ5-CC3 = $3148, BV#-OQ5-CC4 = $2396, BV3-OQ6-CC2 = $3101, BV3-OQ6-CC3 = $2320, and BV3-OQ6-CC4 = $1766. These numbers are for retail in USA of a 12 bore SXS made 1890ish to 1960ish. 1920's fits to these numbers. 20 bore SXS is getting around 150% - 175% premium to 12 bore recently. So, multiply the $ figures by 1.5 to 1.75. There is a 2X spread on the numbers, but at least that is the ballpark. More complete description = more refined price estimate. Lake was an Australian importer as I understand.
