Going to be displaying at a show in early March and hopefully a couple more this summer… I usually have a couple whistles on a manifold from my boiler but would like to add a couple sirens as well because it seems to be a hit with all the kids and really grabs their attention. Somewhere I have a P31 from Jin but I don’t know where somewhere is… 😂 so I would also buy one of those if anyone has one available. Thanks!
