just saw these on ebay and couldn’t resist them, they will look a treat with the Hudson on O27
However they are heavy things! They have cast trucks with a roller on each truck.. they appear to have been on display a long time and although I’ve applied some WD40 and contact cleaner, the rolling resistance is considerable.
My modern 0-8-0 can hardly move them! The Scout 2-4-2 needs a gentle hand on the lever to get them going, but copes well enough when they are moving. Now, wheres that Hudson?...
