The B-Class engines have turbogenerators of varying types affixed to them to power the headlamp. Upon asking around, it appears that the one on our prototype 777 at the Delhi museum is either a re-branded Sunbeam, or a copy thereof.
Fortunately, Ken Schroeder, a well known live steam supplier in the United States has just finished castings for a 3 3/4" scale Sunbeam, which is just right for our B.
We received the first unit sold. It is a dummy, but there are plans to make it functional later.
The unit is currently en-route to New Zealand for installation on the B before big convention in January.
I have added a new gallery of photos I took of the genny before sending it off, as well as a picture of the one on 777 in Delhi. (painted 'preservation white') Here are some highlights. The ruler is a 150mm rule.
