Hello all
quarter inch for Life Steam is on the small side but there were several manufacturers over the last 90 years.
Roy Ashley of SF offered a NYC Pacific 1928-30's .... also offered the Timken Four Aces Northern that had to be a heck of an engine never seen that one yet
Below see pictures of the Pacific .. sold as a casting kit or you could have one built up for you around 250 bucks which was real money 90 years ago.
For the same 250 as a base price you could buy a small engine from Neff.
Here is a Neff American.. which proved to be a little small as most of his Engines
Are Pacifics and larger.. right up to a big boy it's a pretty sight he made roughly 75 engines from the late 30s to the 50s run on liquid propane one day I'll fire up off the engines.
Across the pond the British made lots and lots of O scale engines some of them are quite reasonably priced and fun to play with.
Cheers Carey
