I have 3-DQ 220 reels,2 have the small brass ball lever.1 has a larger silver ball lever.I assume the larger silver ball lever is a newer reel? I was just curious when it changed,I kinda like the brass one better when it's polished up,no biggie.
DQ changed a few things over each series of reels —-
The 220 Finessa was part of a (7) reel series and was introduced in 1967 —- and ran through 1973.
Then the next 7 reel series of "N" numbered reels were introduced in 1974.
If an angler could/would/could only afford (1) DAM Quick reel —- the tough 220 would cover most fishing conditions from small guys up to salmon & steelhead.
It is an outstanding reel in engineering, materials, and features. They are not expensive —- but very high quality.
If restored and serviced properly —- they will go another lifetime.
Best, Fred
