Don,


I've had some fellow hobbyists question the drawing from the BFRC and the more I think about it, I share their questions. I have original knobs as do others and of my and some others' knobs, none have a domed outer surface; all of them are flat. While not a statistically valid sample size, twenty or so knobs cannot be completely ignored nor are they likely to be old reproductions.


I realize that you are only sharing what is on a eighty-five year old drawing not of your making. So, the question is: what has been your own experience with original knobs? Two others are: what's a staked washer in this application if you know? and what do you think was the timing of the switch to the larger diameter knobs?


Thanks.


Dave
