Hi. It looks like an old 5000B model. 3.8-1 tranny, a couple of hard 'phenolic' drag washers, with a 1st generation snooze alarm. This drawing should work. WHATEVER you do, do NOT pull the yoke spring out of that square keeper by the push button !!!! (5119-4056) If you do, you will rue the day, and fight with it for a ~very~ long time.
