Quoted from Spyder138:
Bally Signal listed for sale in Sacramento. $450. sacramento.craigslist.org link[quoted image]
Signal, Sr. and Signal, Jr. are very good prewar titles. Nine sequential, mechanical railroad flags activate to advance balls, accompanied by a pleasing railroad crossing bell. Aesthetically attractive Harry Williams design, with that "just one more play" addictive quality.
This one appears to be the larger version (Signal, Sr.). While the junior version is more compact, the senior version is a good choice for collectors who don't mind the larger footprint.
The senior version has a more substantial scoring card casting. This example has the correct legs and the original coin door. At $450, it's an excellent value.
If I didn't already have a Signal, Jr., I would be buying this game.
