How could I find out about my bicycle brand/model? I've purchased a bicycle on eBay thinking it was a Colnago as the stickers/item description would let you believe. 



Unfortunately, looking at the bicycle a bit more closely, I'm pretty sure this is not a Colnago at some clover-shape embossed stamps are missing on the frame...

The bicycle has got chrome forks and some numbers engraved on the bottom of the frame (see pictures):

I'd like to know where my bicycle is coming from and what made/model it is. 


Has anyone seen a similar bike in the past?
Would you have any idea how to find out more about this item?
I share your doubt that it's a genuine Colnago.

I Googled "when was colnago clover leaf embossed" (you could try that with the .au removed also).

The hits show plenty of people asking such questions, and a couple of the hits seem to provide valuable answers

How to identify a fake or genuine Colnago


Both of these suggest that without the "Club" embossing, it's not the genuine article.
