My Ebay store has points and rotors, go to fa_consigners on Ebay, simply type in Graham in my search window. The numbering system in my 1931 Chilton catalog uses Shurhit numbers. The listings for 1929 is Graham Paige Model 827 & 837 for the dual-point application. I have the 2 point arms which are #813238 and the point bases are #825452 & 820558. I have those at $35.00 per NOS set postpaid. Very odd. I have several sets in stock but they haven't been on my store in a while. I'll work on that tonight. I've just listed the Graham points on my store.
The cap is # 825430 and the rotor is #37598. I may have the cap, not sure on that rotor. My store shows pictures of what you need.
