Horn capacitor needed for 36 Ford

[gulfoil]

I had a thread earlier about how my dual horns quit, and it turned out the capacitor was dead in the driver's side horn.. Pictured is the capacitor about 3 inches long and 1/2 inch thick, no markings of any kind. Does anyone know of a replacement, or the parameters of the capacitor, or a horn rebuilder that may have this unit? Thanks for any information!
