I've been bitten by the 'Play-boy' bug a few times.
Nice looking engines. I wish the boiler had a larger
capacity....or a pump to top off the boiler during a
run.
If the heater is dead you might consider 'band heaters'
(35mm X 3mm) on EBAY. I used them in an Empire B31, a
Playboy, and an Elektro engine. I bought 380watt units
but please note that the real wattage could be less.
Also, the whistle should be earlier version.
Not easy to find one to buy. A quest!
As soon as you get it running put up a youtube video.
Good luck,
Wayne
