Swift double flatbeds

I'm looking for more information regarding these swift setups. I would love to see more photos if you have them. This is from a picture that was taken back around 2007.

 

Around what year did you see them with decals removed? The reason I created this thread is because I'm interested in buying a set of those trailers, and as far as I know swift was the only one with the aluminum Ravens doubles. I've called Swifts equipment sales and the guy I spoke with had no idea what I was talking about. He said that there was no record of any ever being sold. He also said the best thing would be if I could get a unit number.. I do know of 1 guy that has a set of Ravens doubles but I'm not sure if they are former swift trailers. I haul hay in Arizona and California and pull doubles, and I would really love to acquire a set of aluminum doubles. Weight is a huge factor for us. I know that the one guy that has them hauling hay his tare is right around 23,000.

 

It's not difficult I have a few sets already, I was just hoping to get more information regarding the Ravens that swift had. As far as I know they where the only company to have them. But finding information on them is like finding hens teeth. If they don't keep equipment for more than 4 years is it possible they scrapped them? I have never seen any for sale.
