Great rifle and an even better woods cartridge. Made from 1936 to 1950 when it was replaced by the 760. They made around 77,000 of them altogether. Yours was probably made in the mid 1940's. There should be a two or three letter code on the barrel indicating month and year produced. You can google the Remington Society for your year of production. If it is in decent shape you can get $500-$600 for it as in .35 chambering they are sought after.
