I found this cleaning out my father's house. He had over 100 tanks. This one has been in the garage for many years. It hasn't had fish in it since the 1971 Sylmar Earthquake. There is light rust on a couple of the corners. Looks like it will polish out. No pitting. Should be resealed due to the age. Easy tank to restore. Please check my other listings for vintage items! Thank you for your interest!
