I can not take credit for discovering Ertl die cast toys...St Paul stream has done wonders with them!
But searching tonight for something fun to power I happened upon there scale series hit and miss engines....now it is not technically correct for a steam engine to power a hit and miss engine...however I don't care....I love hit and miss and to have a nice metal one spinning on display would be fun for me. I will not know till it comes but think it will need disassemble then ream some bronze bushings into frame, make a straight steel axle and Chuck flywheels up in lathe true and ream snug fit for axle...then if get fancy turn up some tiny functional oil cups!
It's a project accessory but more visual interest than some of the Wileso offerings.
When I find a good deal I will purchase and mod...if it turns out I will post pics.
