Actually, I was the guilty person that asked the question about the rarity of: “5 Gal” vs. “10 Gal” in the “showcase forum”.
http://www.oldgas.com/forum/ubbthreads.php?ubb=showflat&Number=292498#Post292498Loyd was kind enough to expand the question with a new thread.
BTW, I was not looking for historical data (how many pumps Fry company produced) rather an answer based on data from all collectors over the years. Either way, great answers so far as I will take any information I can get. Thanks to Dave & Jack as well.
I am already hooked on the “5 Gal” one.
