I got a 502 today. At the end of the day went to a friends house for a visit. On my way home he gave me a 502. It is dirty with a little rust but it works fine even with about 20 years of dust on it. I will paint it red to match my camper. I will have to change out the fill gasket and pump gasket. When done I will post photos. I am sure all know what a dirty 502 looks like. Now if I can find a 500 and a big top lantern. And the time to rework all the stuff I have. Spring is at hand and my camper needs a polish.
