Peter, You should have waited a week to go home and come east to see the fall expo at Coolsping Pa.
Went to the Coolspring show yesterday and here was a small R-H similar to Peter's for sale. Pretty decent original paint, ran very well. twin heavy flywheels, $7500 FIRM Owner was asking 10K all summer for it. If anyone is interested I can provide contact info. Owner/seller is in Quebec Canada.
Other English stuff for sale
Only Lister for sale was a model D in a sad state of affairs. didnt ask price
R-H Mark CR elevator engine , bare, no extras looked like it would easily run. 4K
Huge Crossley town gas engine, didnt ask price.
If a person likes H-D British motive power Coolspring Pa is the place to see it both running and for sale here in the states. Lots of engines on display but not for sale that I did not include here.
