Colt Woodsman ..is a nice gun ...
and if it were not for that - addition - on the side / in very clean condition its about a $1,000 gun ...maybe a little more...
In that condition ...I wouldn't buy it even for $ 200 ...because there are so many around at my local gunshows....in better condition / its a gun that while not "real common" I can count on seeing at least half a dozen at most of our local shows...in excellent condition ---although it might vary around the country.
There are a lot of other "match grade .22's" out there as well ....from High Standard.../ S&W model 41's .../ Browning Challenger.../ and then there are the new guns - or newer guns from Hammerli, Pardini, etc... like on this site for Larry's Guns....
I'm not a "purist collector" either...every gun I buy / I shoot ...even if I bougth it new in box unfired...like an old model 27 S&W revolver...I'd still shoot it ...might shoot it a lot !! So I'm a shooter at heart ...vs a collector../ I just don't want to see you get burned on this gun ...and see 10 more of them over the next 6 months in better shape...

Its up to you ....but I'd pass on that gun / because if you try and sell it down the road...I think you'll have a really hard time selling it / and even if you had a good shop re-do the finish / and hopefully wet sand out most of the scratchings...losing the old patina on that gun is a sin too.../ making it almost unsaleable.
A case in point...a local shop in my area...has a K-22 masterpiece revolver, 6", .22 ...S&W ...and it has a re-done nickel finish on it ....and its been in the case for over 6 months ...and not a single bite on it. A lot of us would have sucked it up in a heartbeat ...if it were original...and I think the shop has it marked down now to around $ 400 ...and still no takers on it...
There are just too many old guns still out there for sale...
