What a beauty, I'd keep the tacked tom wwith the kit, they are far more user friendly than people make out I use them now and then and they may limit tuning possibilities a bit but they can sound great.
I would be loath to sell this, radio king kits have something special about them and this one is from a very interesting period, just on the cusp of the U.S entering the war, the beavertail lug came in in about 1940 and it is not unusual to find cigar and bevertails on the same kit.
Beautiful kit
