What was that Stuart boiler fired on ..... coal?
Looks like it will be a nice S50 when cleaned up Nick, need to get a large BIX for it now if you haven't already got one.
I don’t need the S-50 as this makes number 5 here...

I bought it because I needed another boiler and I wasn’t expecting the seller to accept my very low offer.
I have the long BIX which would be enough for running the engine unloaded, but would love to get the long/wide one I have seen.
