Any suggestions for a replacement horn for a 2343 diesel? I found several on eBay, including an "ACME metal buzzer, burglary alarm, bicycle, door bell horn," a "Delta style 1.5v bicycle tank horn," and some others that all look like my original. Anybody know if these are okay? Also, I see that Lionel introduced an Electronic Horn Kit (6-8190) somewhere along the line. Any info on that? Would it work with an old school KW transformer and would it fit into the dummy 2343? Thanks, Bob
