I just found 4 more recoil springs I had for the R-9S.
These are all brand new.
$5 for 2 or $9 for all 4.
S&H $3.
Also have an almost-new (only used 3 times) R.W. Hedley "Chopstick", in brass. A bargain at $5, again with S&H $3.
S&H isn't arithmetically additive, that is, it would still be only $3 if somebody buys all of the above at once. It basically has to do with the annoyance of wrapping, labeling, and making the trip(s) to the post office or UPS office, as well as paying postage and perhaps insurance.
PM me if interested.
