Hi Trevor thanks for that.
I don't want to get invovled in a decision to make/commision a boiler as I have ample to do – I was just wondering if there were commercial coal-fed boilers available off the shelf for use with Stuart engines as this would suit my friend's dad best.
Although I've never used Lynx, I've heard a few tales about them so would not feel comfortable recommending them. It looks as though GLR are going to be best. I know Western Steam is highly respected, but the lead times rule her out.
Some less helpful replies – as someone who has commisioned loco boilers from MaccSteam, I'd kinda worked out I could have had a boiler commisioned from scratch, not very helpful. I won't describe it as going off on tangents though, I have more manners than that!
Cheers,
Mike.
