So my dad picked up an ASM 1851 Navy in brass frame with the wood presentation case, powder flask, brass ball mould, etc. several years ago and asked me, now, if I want it. He's just not interested in it anymore. It's never been fired, but I remember it had a broken bolt spring when he got it, so he got it for a song (I fixed it for him a few years ago). I want to give him close to the value of it but have no idea about ASMs. The brass pietta at Cabelas is $130 at the moment, without any of the accoutrements. Any idea on value of this set?
