Bennie, The reels were lighter than the fibre ones, the 2 plates/ disc's where press rolled from stainless plate with ridges and contours to give it strength. also a pattern was cut out for "Spokes" to save on weight.
These reels last a lifetime, I have used mine delivering boats all over the world, many many trips up to Mozam etc for the past 16 years and it is still as the day I got it. My fathers few he uses on his yacht has seen 3-4 times more use and again still in perfect condition. Nothing to rust and seize, Vesconite bushes. We used a old flip flop tied to the shaft as a breaking pad, this allow's us to set the rod up for trolling and leave it unattended. There have been many many fish over 30KG caught with these reels.
Problem is now the factory set up has changed and we do pretty much straight production work and dont have the time to make these smaller items. We regularly have the commercial, or other fisherman asking us to make just a few more but its just not viable. Also remember that we talking old school 1:1 ratio reels they were meant to Last, so were mostly sold to the commercial guys, once they had 10-15 reels on a boat we didn't see them for 5-6 years.
Ill dig out some photos and post ASAP so you can get an idea of what they are like.
