They were a little oddity to FEC Railfans since these were the only Cantilevers of there type on the Railway, (there could've been others in the past, but this is as far as we know). These Signals were apparently made by Walpar Industries Inc, these were installed at this crossing sometime in the late 70's or the early-mid 80's.
This is the last Google Maps Capture of the Crossing. They've since been replaced.

Here is a video of the Crossing in action.
Many other Signal fans say they look a lot like older Safetran Cantilevers, which they do.
Has anybody else seen Walpar Equipment installed elsewhere? They're still in business, but I don't think they currently install Railroad Cantilevers anymore.
Here is they're website:
