Just a helpful horn list for horn creators on the forum.

Nice find. Thanks for sharing.

Let's add to that list
Leslie
RS3K
S3K
(R)S3E
(R)S3B
(R)SU3L
S3J
S5D <---- VERY rare, basically a Leslie copy of the M5
S4T/SL4T <--- S4Ts were a 4 chime horn ONLY made for Amtrak SDP40Fs, and very few are known to exist, about 6 IIRC, the SL4T is even rarer, with only 2 left in collector's hands
Prime PM-990
Prime PM-920
Nathan
K5LLA <--- an annoying noise cannon to anyone with musical tastes or who wants to sleep at night
K5HL <--- ones on BNSF H2 ES44s are sandcast and generally mellow
P5A <--- Came on Amtrak F40PHs originally and P30CHs
K5L <--- same thing as a K5H but on a low manifold
K3L <--- VERY common on CN locomotives, this is the "Canadian tuned K3LA" that you see everyone talking about
Nathan J3 <--- Fairly rare, mainly found on CN snowplows. Has a very "haunting" sound when heard at a distance
Hexatone H-5 <--- The grandaddy to ALL modern locomotive horns, it was the first multi chime locomotive horn ever made, very rare too. Something like 10 left in collector's hands
As a side note, if there's a one off horn, like a K5LLLA (yes I've seen it exist) it was probably done by a shop employee for shiggles or if you see it for sale done by a collector. Weird bell arrangements happen and honestly they're not worth freaking out about unless it's like a K55555H (Also seen it happen, s/o to Zach). Remember, there's also multiple kinds of single and double chimes from Leslie that I didn't bother putting on the list, RS2A, RS31, etc...
Good luck out there!

That sums up the K5LLA well.
