Hot Rods Info needed on master brake cylinder

I have a Wagner-Lockheed master cylinder. Cast number is FE 1743. Wagner says it has been cross-reference to a new number F3241. Application shows mid 40s to mid 50s MOPAR vehicle. Need to verify as I am going to have it rebuilt. I know it's old but I'm building/restoring an old school 29 A RPU and I want to keep it as it was in the 60s. Any info re the unit and who could rebuild it would be greatl appreciated. Thanks

 

white post restorations can rebuild it using a stainless steel sleeve.
