Default Nathan K3HA, and 80e 4wd conversion crossmember

Its time to get rid of my big horn. I guess im getting too old for it, and I barely use it any more. I could also use the money to fund the work truck...
Its a Nathan K3HA, and I'll include the 1/2" valve. This is a serious horn. It is a REAL train horn, not the dinky ebay knockoffs that are shiny and chrome. This horn shakes the damn ground and can be heard for miles. I have run it at 200psi and it is ungodly loud at that pressure. You need at minimum a 5 gallon tank to feed this beast. I really want to emphasis this is as loud as you get when it comes to air horns. Go sit next to a train track, then keep in mind trains run 120psi, and I have run this one at 200psi. I just took it apart completely a few months ago to clean it and it looks perfect on the inside. No plastic anywhere, all metal parts. The outside is painted silver, and the inside is black. I bought it about 2 years ago from a guy that rebuilds them.

Here is a comparison to my old ebay train horn. This is the difference between a knock off "train horn" and the real deal.

Here is a quick vid

This is the same horn that is uncoated, without a valve, $950 from hornblasters. SOLD!

Also selling a conversion crossmember that I cant use for my project. This is for a 4wd 80e conversion. A friend that has a machine shop made this for me, but the 99 style. Its a directly bolt in for you 4wd 60e guys that want to run an 80e. The bracket is fully welded 3/8" steel. $100+ shipping

Thanks guys, you should join your buddy John, horns are a lot of fun.

For anyone curious, the K3HA and K3LA have the exact same sound but the H and L denote the manifold design. H being high and L being low. This horn lends itself to fitting right here exceptionally well...

I have my other horn, an 24" truck horn, and I actually use my air system quite often (impact speeds up a lot of stuff, and filing tires is very easy). If you are really interested in the whole system, im sure we could work something out. 5 gallon 200psi tank, viair 420c, viair 480c, air-water seperator, dual pressure switches, and about $100 in fittings just on the tank.
