This is a great set of Kahlenberg D2 Ship horns. I took these to a friend's home and tested them. They were EXTREMELY loud. Offensively loud. The longest of the two horns is 20" long. Each of the horns bells are 7 1/2" across. Each of the bells of the horns have some dents. The largest one has a few more than the smaller one. I think they're obvious in the pictures. I haven't attempted to clean these, but I'm sure they would really clean up nicely.These horns are all brass. They are very heavy. I would estimate they weigh 40 to 50 pounds, so shipping could be a little expensive, but I promise I will only charge what I'm charged, and no more. I'll be shipping them UPS.I know almost nothing about these type things, so if you have any questions please ask, and I'll do my best.I'll be listing a couple of brass ship spot lights or search lights soon, so be watching my other sales for that.Thanks for looking.
