It is a slight mixture of parts. Yes the center section is 48 as indicated by the 1-1/32
The linkage from the throttle to the upper section, for the choke, is 97 note the small hole on the upper side. If the upper section has a spring loaded button to fit in the small hole in the linkage then it is also 97. The cast base section??, the linkage at the throttle if it has the "W" and "S" post for the throttle linkage is also 97?? I believe the 34 model 48 is not marked with the "48" until the 35 year. Stromberg was a supplier to several car companies so Ford started having the Carbs. placed on their cars, identified with the car model prefix 48 is the model number for 1935. This was due to Ford starting a rebuilding business for only their own assemblies.
If you want a rebuilding kit go to the Stromberg web site and order there or contact Max Musgrove at Stromberg. If you want a more detailed exam post more photos of the top with the linkage removed, the throttle at the base.
