I have a couple old 300's as well as the modern version. The older ones I had cleaned and lubed. I got them off ebay, and aren't as good as described. I will find one of the older ones in better shape, more for nostalgia than anything. I primarily use the Pflueger Presidents lately.
Proud to have served with and supported the Units I was in: 1st IDF, 9th INF, 558th USAAG (Greece), 7th Transportation Brigade, 6th MEDSOM (Korea), III Corp, 8th IDF, 3rd Armor Div.

I had two of the 308's and sold them to a friend (probably close to 50yrs ago). He wanted them for distance casting tournaments at our local Sportsman's League. He took the bails off, & spooled them with very light mono (probably 2lb test). I never found out how well he did with them, or even if only he used them or he & his brother used them. The reels were "well used" when I sold them, but I really can't remember from whom I got them ... and I don't remember actually ever using them, myself. I think I was still in the spincast game back in those days (for Crappie), and just a newbie to baitcast reels (for Bass).
