Hi Guys

Here is what I have learned, from your input and Searching for a while and help from Don Mcclellans restoration site


http://mcclellans.com/Philco16BCathedralRestoration.htm


Now we are referring to the Cathedral Model 16B early

There are two sizes of the Knobs  Medium and Large  P/N 03064 & 03063 . (from parts list found in Gernsback Volume IV page 170 on.)

The Parts list refer to the Medium size Knob as The SMALL Knob 03064  The Large knob as 03063

Now I believe both style of the large Knob could be correct.
Screw in center Face ( The Tuning shaft does indeed have a threaded hole in center)

Now Don has been kind enough to send me a Photo of his Large knob, which shows a set screw in the side of Large knob.

The Knob sizes as per Gary at Playthings   Large 1 1/8 X 5/8    Medium (Small) 7/8 X 3/8

So I believe the Knob question has been answered.


Thanks to All
Bob T
