I observed something interesting the other day, when I saw two gold and silver (silver body, gold keys) Conn New Wonder Series I saxes sitting next to each other. One had the inlaid gold in the engraving, which I was expecting, but the other didn't have any inlaid gold in the engraving at all. To top it off, the one without the gold inlay had a gold microtuner, while the one with it had a silver one. Any ideas what's going on here? The serial numbers were about 1600 apart (around 126-128,XXX), and the newer of the two was the one without the gold inlay. I snapped a picture of the one without the inlay to show what I mean...I'm just confused why there's differences in finish...any thoughts on this?
