Nope. Somewhere in the mid to late sixties they went to nylon or plastic like a lot of others but for some reason - and maybe that's a drawback of our arid climate - whereas you get really badly rusted, we get cracked a lot sooner? - the Brother machines in that late 60s to 70s range moreso than other brands for some reason have all been parters for me because of cracked gears and cam stacks.
