D.A.M. Quick question

[billfish]

I'm new here but that should have gotten somebodies attention!! I have two Quick reels that look identical with the exception of the handles. I did not buy them new but have had them for years. One is marked as 330 and the other 331. Does anybody know what, if any, the difference is?
Thanks in advance,
Ron

there might be a different number of ball bearings ? , the gear ratio . and the clutch system . i wouldnt go with D.A.M RODS , but i dunno bout there reels ( bit too heavy ) ..
