Pre-war Marlin Model 90 as made for Sears. There is some parts availability from used parts dealers. I have some, Numrich has some. 20ga brings more than 12ga, but you are still looking under $400 in top condition. RARE gauges like .410 (in this model) and the .22/.410 combo bring considerably more. sales@countrygunsmith.net
