What is it chambered for? If it is a .30-06 length cartridge then it will be a 111 if it is a .223/.308 length cartridge then it is an 11. Some parts fit both universally some do not. If the part you want involves the stock, bolt or magazine then you'll need to get action specific.
I don't know how I missed the .30-06 in your first post. Makes yours a 111 TH.
