Two Line Yellow 500 set Western Electric

[tell302man]

I need some help. I saw a nice clean yellow Western Electric 500 phone a antique mall for 20 bucks. It was a two line version. Are these sort of rare? I passed on it because I already have several regular yellow 500 sets. It still had its orginal Bell System yellow four prong plug as well. Should I go back and get it?
