For free just pay shipping. I have a 150M seat frame, appears to be in good conditions. I'd like to donate it to a members who has a use for it, to repair his broken seat, not just to collect used stuff for future resale.
It is the narrow frame that fits the 74 and later 150-152.
Frederic I just talked to my IA and he told me that the FEDs are not approving 337's like they used to. I think I am gonna pass on your seat. Thanks anyhow.
