FS: or WTT Size 52 Gorilla Zengang frameset - 500$

I have for sale a size 52 Gorilla Zengang frame. Double butted columbus spirit. 54tt, 52st. The original paint was badly chipped so I rawed the frame and had it custom powder coated. I bought this frame on craigslist under the pretense that it was a size 54 ie. 55tt and 54st. I stupidly didn't bring a tape measurer or check the bottom bracket when I bought it. Only when I put the bike together did I see "52" stamped under the bottom bracket shell.

There is one small, very shallow dent on the top tube that is only visible under extremely close inspection. I had a hard time bringing it up on camera. Obviously it doesn't compromise performance. Otherwise the frame is absolutely flawless as I just picked it up from the powder coaters 2 days ago.

I am looking to trade for a steel frameset in a size 55 or ideally a 54 EAI bareknuckle. Or 500$ plus shipping. I am located in Toronto, Canada.

Thanks for your time.
