Ken, that was an enjoyable video - and applicable use of the Lionel Rockville Bridge. I have one still in the box and awaiting retrofitting somewhere. When I got mine, I noted that it doesn't come with mortar lines as shown on the box and catalog; I can mortar brick buildings fairly straightforwardly using Robert's brick mortar mix, however I don't know if the "brush on, dry, and wipe-off" method would work on the bridge or not, given the myriad crevices. Nevertheless, it's a very neat bridge and our hobby can use more neat accessories in that historical tradition. I really like how you raised your bridge, gives me ideas on using mine.
