1932 Dunhill Bruyere U.S. PATENT 1861910/32

I've just acquired a 1932 Dunhill Bruyere U.S. PATENT 1861910/32 with the Vernon fitting and inner tube in tact. If any Dunhill experts could verify that I am interpreting the coding correctly I would appreciate it.
The nomenclature is light but I am hoping it will photograph clearer once cleaned up. On the right side of the shank it says, MADE IN ENGLAND12 (the 12 is underscored and half-size of the D). On the same line in full size is T35. Is the T35 the shapes code? On the line below is U.S. PATENT 1861910/32. Here is a link to the patent on pipephil:

On the left side of the shank is the Ao for the Bruyere finish and it says DUNHILL over LONDON.
The stem has the single dot which appears to be more of a tobacco color than white. On the opposite side from the dot is stamped REG No ( the o is underscored and half size to the N) over 65438.
I would appreciate it if someone could verify my coding or correct me if I am incorrect. It appears to have been smoked very little. For now I'm just going to gently clean with a damp cloth and see if I can photograph the nomenclature with better lighting. These photographs were just taken with my iPad and are rather poor but will have to do for now.

Dave and George, thank you both for the confirmation and other information. Until I got into the coding I thought I remembered off the top of my head that patent date nomenclature would date the pipe to be no newer than the late 1950's and I thought to myself that someone might be looking for a birth year pipe of that era. I never would have thought it would date back to 1932. If someone needs a 1932 birth year pipe they better find one soon!
