Hi folks

So I scored this nice little retro mtb from the tip the other day. I think it's a Carrera Katmandu Carrera Katmandu - Reynolds 501 Magnum - Shimano Deore LX | Retrobike - as you can see from the pics, it's near identical.

The trouble is, even though I'm satisfied I bought it from a legitimate source (the tip), it's hard to deny that the evidence is strong that it's been stolen at some point.

All the decals (except the reynolds sticker, funnily enough) and the serial number (I presume, because it's not there) have been removed.

I originally bought it to clean up and sell, but now I'm beginning to wonder about the ethics of it. What would you do?

Thanks
