Noble was in Haydenville, Massachusetts, and was in business from 1946 according to one source until 1971. The Captain's source says 1950 - I have seen that date as well. They made very plain Jane - utility firearms for several "catalog" companies.
What you have could possible be a model 40 or model 50 or model 60 or model 65. If it has a round "port" on the back of the trigger gard - it is for a key lock fire control system and if you don't have the key it won't fire and it will be one of the "clp" models. If you will describe the gun as completely as you can -- either the Captain or I or someone else on this forum will try to help you out.
There is almost no collector interest in the Noble and you would be hard pressed to get more $125 for the gun in very good condition.
They were well made and are perfectly good "shooters". Take it afield and hunt with it.
