I have a master cylinder for the 57 to 59 Skyliner power brakes with the 1 1/8" bore if anyone is interested.
The Ford part number is B7A2140B and the Wagner Lockheed number is FE23237.
I purchased it from one of the vendors advertising in Skyliner magazine as NOS. Upon receipt it was seized up from setting so long. I got it freed up but it was scored. I sent it to White Post Restorations to have it re-sleeved. I paid around $125 to purchase it and about the same to have it re-sleeved.
I have sold my car and have this listed on Ebay if anyone is interested.
