Bashsea twisted protein skimmer question

[jp1986]

I got a second hand Bashea twisted protein skimmer and I am trying to figure out which model it is. There are no manufacturers stickers or model numbers on it. It measures about 35" tall. I am hoping to figure out which model it is to get an idea on a price I could sell it for as I use an in-sump skimmer. Any idea on what model this is?

Unsure. Check everywhere for a small sticker or serial number!!
