Thanks for the help Tinindian, I do appreciate it. I'm quoting from page five of the original owners manual that came with my '29 Pontiac. " Unlocking and Locking the Car" The Pontiac Six is equipped with the Delco-Remy Dual lock or combined ignition and transmission lock, which will prevent theft in the great majority of instances, providing the car is actually locked. It is suprising to note from reports of insurance companies how many automobiles equiped with locks are stolen due to carelessness on the part of the owner in leaving them unlocked. The surest way to prevent this regrettable experience is to lock the car before you leave the seat To Operate Lock: 1. Insert key 2. Turn key one full turn clockwise to on position. This unlocks transmission and turns on ignition. 3.To stop engine turn key 1/4 turn counter-clockwise to off position. 4. To lock transmission and to remove key, turn key one full turn counter-clockwise to lock position. The second owner bought this car with about 17,000 miles on it and I'm the third owner. It really looks like original equipment to me. The other end of the lock is an integral part of the ignition switch as far as I can tell. Judging from how hard it was from the day I bought it to turn the ignition switch, it's always been a bear. I can easily imagine that these locks would have been yanked fairly soon in the cars lives. Or possibly this is an early part of the big six run and the lock was dropped right away. It is serial number P646566 and is titled as a 1929, but I read where you said many had no official year attached to them until later. The funny thing about this "lock" is that both ends are crimped to the tranny and ignition, no threaded parts that I can see. Wouldn't that be unusual for any 1929 car? Also I have looked fairly hard for a method to lubricate it and haven't found anything yet, although I haven't broken down and remove the rest of the floorboard, just the very bottom piece. Thanks again for the help,Tinindian, I guess pulling the top off the tranny is going to be the only way to get at this thing! Jake29
