[Hallicrafters] S-53A BFO COIL

[Mr. and Mrs. Magoo]

Someone removed the BFO coil T-13 from an otherwise very nice S-53A.  Can 
anyone give me the dimensions of this coil and, if possible, the wire size 
used to wind it?  It does not show clearly in the photo of the underside of 
the radio.  Is the winding scramble-wound or linear and layered?

I will try to make a replacement if I can obtain the above information.

Thanks.
