To clarify my previous comment, some of the railings were welded and some were bracketed.
I did take RAW images with my real camera. I am uploading some quick cell phone images to give everybody a rough idea of the design of this bridge.
I field visited this one today. It is indeed a historic pin-connected Queenpost pony. The tubular railings were welded on years ago. Floorbeams are marked "Cambria". It has inriggers, but no outriggers.
I am not sure where this bridge came from. This listing may technically be a duplicate if the bridge corresponds to one of the unknown listings on this site. Regardless, I am glad that this one got saved. Queenpost Trusses are become less common all the time, so it is nice to see one get preserved.
