Bob,
No pictures of the Russian versions of Biller, but maybe someone else can fill that gap. I would like to see them myself. It looks like Biller had a complete system and if I remember correctly, it was not that long ago, they went out of business.
Here is another version of the Biller crane...
I scan the U.K version of Ebay and have never come across any examples to look at. The only ones found were via that link. There are some available through a Google search of images. Here is a link to a Dutch show where a demonstration layout of Biller was set up. Funny how one thing leads to another.

The author of the piece says: "The marvel of the locomotive is the control button on top by which it can be switched on and off and the direction can be changed. It also has a neutral position, whereby the gears are disengaged, so that the loco can be pushed without using the driving mechanism. Both the clockwork and battery locos are fitted with this button." Hmm, a push button rather than a lever.
A complete set..looks like some great lithography.
