Ebay seller has a Boston Wheeler street light for sale Item
https://www.ebay.com/itm/Vintage-Wheeler-Boston-Oval-Industrial-Grey-Enamel-Porcelain-Light/303102228344. It's not the older rounded Wheeler from the 40's/50's though. Been trying to get one of those for over 2 years but they seem to go to the collectors in the Northeast and West coast..
