I also thought that bat wings were not sold by merchants back in classic / kunark.
But after researching I found that before kunark they were definitely on a few vendors.
Click Trade supplies / East Commons. Also sold in other zones. I coulda swore they weren't sold in classic , but this page doesn't lie.

This is from the old eqtraders pre kunark.
I remember people selling them is the only reason I didn't think mechs sold them.
Also it was hard to find info back then. Like who sold them. So not everyone knew.
Fish scales is another story I will have to research that. I do remember fishing for hours to get some scales.
