I doubt that any of these receivers are new/unused. Some will show their original finish with various degrees of wear. Others will have been re-parkerized while in Danish service. Overall condition will be much like the stripped Danish receivers which were being sold by Lever Arms and Marstar. I don't know where these have been languishing for the past number of years, but most likely they were stripped from rifles which were torn down in Canada 12-15 yrs ago with all parts, less receivers, exported into the US as parts kits. US law precludes the receivers being imported. Some years ago there was a big kerfuffle about a number of Garand receivers which were seized when someone attempted to export them to the US from Canada.
It is nice to see receivers available at these prices. The Breda and Beretta receivers were made to a high quality line and are an excellent basis to build on. The big challenge now is to round up all of the other parts.
