Yesterday I made the trip to Jacksonville FL (1050 miles RT) and back to look at the controversial tube. It was a good case of be careful what you wish for. The rather nice guy who had it for sale obviously had never been near it with a measuring tape, 56" long not 48". A couple hundred pounds heavier too. On the up side, the corrosion was minimal- light surface only on the tube exterior and only a small area of the bottom side of the bore right at the muzzle. Not anywhere near as bad as it looked. The vent had never been drilled through, only 1.5" deep, although the gun had been fired by a cruise line probably electrically. Best finding was on the right trunnion where it was stamped Southbend Replicas, Southbend, Ind. I bought it.
That's where the fun started, transport cradle had been made for a 48" tube and worse, the tube was 4" longer than the cargo area in my jeep. Finally wrestled it in catty cornered and inadequately secured the monster, could just see it deciding to come visit me in the front seat. Made the Jeep sit a little funny too. There was a perfectly good trailer with tie downs and a big cradle back at the house-damn. I will post a few pics when I figure out how to get it OUT of the Jeep. Wearily, LS
