I bought a faked Pogliaghi. I posted it here and learned it was actually an MKM frame before I bought it.



Here is the thread.
Is this a real Pogliaghi???

The frameset went to T-Mar. That frame was much rougher than yours. I think yours still looks quite nice (decal placement not withstanding).
Most people will buy it as a cool bike. Disclose what it is. If the new buyer cares, he/she can make the effort to learn who made it.

Who knows, it may turn out to be a score for the new buyer!
