Coheley 5, sorry to have used your thread to show off, but this may help. You didn't specify your price range for the pole you're looking for, but if you'de like a decent one at a great price check out this auction:
cheap barber pole Bid through Old Gas of course - 230570247110
If you can get it for under $150 you stole it, under $200 you made a great buy. The most important thing when buying a pole is to look for a good glass. This one is a Marvy 55 and is relatively unchanged since 1949. The glass is 6 x 16 and would cost you over $125 to replace if it were broken, and I don't think this one is. The shipping is cheap too.
If you want an older, more collectable and better looking pole, get a cast iron/porcelain pole, but it's going to cost you more up front and a restoration will be considerably more.
