Bridge rail for overhead crane

[andrew hawkswell]

I am looking for two short lengths of rail for an overhead travelling crane. It is not a profile I have met before but am told it is called "bridge rail". I can fabricate something from bar and angle if all else fails but I thought I would ask here first in case anyone has any they want rid of or knows where there is some. I need a 1 metre and a 1.5metre length, and the profile is as per the attached photo and sketch. Please PM me on here if you have anything suitable,
regards
Andrew.
