Picked up an Os40 fp today. Got home and compared it to my other one ,realized the case was different. It is the iron/steel earlier version(1986?). Is this worth working with or should I sell/trade it?

uh,, you can give it to me 
actually, with my experience,, the iron piston version was actually a better stunt motor than the later versions

gee,, what a great offer,, uh,,
ok well, maybe not,,
but hey thanks anyway LOL,,
most of my stuff now is pretty quiet when it flies,, ( excepting the pilot who occasionaly makes distrubing comments about his flying)
