A mix of Lockheed and Bendix brakes?? 1951 f3

[Baron_Bergamot]

So on my search for more information on my new old truck I found out from a very knowledgeable member, Stu, that . . .

"Sounds like you have the early data plate, so you might also find that you have the early Lockheed brakes vs later Bendix brakes.

One way to tell is the location of the brake handle. If it is located in the left footwell it is an early truck, or to the right of the shifter it is a late production truck.

This obviously will matter when ordering parts, and is in a large way important because the Lockheed rear drums are 14” i/d while the Bendix are 12” i/d. The Lockheed drums are NLA while the Bendix are available."

I sought to replace the 'widowmaker' RH5s with some 16" front and 16.5" rears from a later 1950s F250 but when I went to measure my rear drums they are... 14". Denoting Lockheed brakes BUT and this is the bit that confuses me... my brake lever is on the right of the shifter.

Either I am reading something wrong or this has the bendix lever with lockheed rear drums??

As you can see in the pics the lever is definitely right of the shifter but the drums by my eye absolutely measure 14". Am I missing something here?
