i am sending some pictures of a Signal Bridge that I purchased at a Swap meet which has come with no manual,therefore, I have no idea how to wire it to my layout. It has no identifying numbers but does have the letters MAR stamped on the top of the bases. I would appreciate any suggestions on how I night proceed. I am attaching pictures of the bridge and the underside of one of the bases. (The bases are the same.)
Thank you.

Purely a guess, but my thought is that the clips under each base powers the two lights on the same side, with one wire from each going to the "common" clip, and the other bulb connection going to each of the remaining clips. A couple of minutes experimentation with a low voltage source (5-15 volts or so, AC or DC) should tell you which is which. Oh, and individual testing each of the four bulbs will reveal if any of them is burned out and in need of replacement. Good luck!

Oh, and that's most likely a Marx signal bridge, like this one on the 'Bay:  |

Can any one give me a better diagram for the wiring of the Marx #1434 signal bridge. The one on Ebay is not very clear. Also is it possible to find a download of the manual. Thanks
