FN Browning Trombone 22lr

I have a fabrique nationale trombone for sale in 22lr. Serial number dates it to the 1920s. These were known as gallery rifles and this one in particular is in pretty good shape. Bore is great and still shiny. Metal still retains some blueing on reciever as well as the barrel. I’ve shot it plenty and is a fun little takedown rifle. Would like to do local sale.
