How much do crystal timers run? I'd like one for display. It would be after I finish the car, so as not to divert funds.
I think Stephen Heatherly is into these timers, but it might be Cameron Whittaker...maybe they'll know
I found mine on eBay for about $20 in it's original box. Have yet to mount it on the car to try it out.
Yes, Stephen Heatherly was running one of these on his Fordor for a while.
Get NOS ones for about $40 plus shipping.

The Crystal timer is fundamentally a good design,(very similar to the original New day timer), but if you actually plan to use an original be sure to get one of Bob Scherzer's reproduction mounting rings shown (black) in the photo above. The original mounting rings are pot metal and most of them are misshapen to the point the timer will not work properly. Also be sure to closely inspect the pot metal brush holder for cracks. In my experience some are cracked and other not.
Ron the Coilman
I had crystal timers on both the coupe and fordor for a while. I removed one to get a look at how it was wearing and found that the pot metal rotor had a small crack. The nut was tightened just enough to keep the rotor from moving. I used blue lock tight on the nut to ensure that it would not come loose. After I discovered the cracked rotor I changed both over to TW timers. Crystal timers but, I wish somebody would reproduce the rotors to replace the fragile pot metal originals.
what's the advantage?
I think this subject of reproducing the crystal timer's rotor came up before and it was suggested to use a rotor from one of the other timers that used this similar flat contact surface since the crystal timer's rotor wasn't all that good a design to start with besides it being made in pot metal.
Lang is now offering the aluminum spacer ring I reproduce that replaces the original pot metal one. Bob
Stephen- I had wondered why you changed to the TW carbon brush. I always suspected that the pot metal rotor would be a weak point. I need to try one out on my touring, until then I'll just stick with the Anderson it hasn't given me any trouble.
Ron- I have the replacement Al ring. The chemist/engineer in me really likes the look of the glass timer. I also like that it's the original formula for Pyrex, not the pre-stressed soda/lime crap they are trying to pass off now.
Pot metal can be an interesting beast since it was not a set formulation, but whatever was left over or lying around. I work on Orthophonic Victrolas as well and victor too was using pot metal at this time. Some of it just crumbles in my hands and others look brand new with no noticeable deformation or deterioration.
