Creedmore I just picked up a mod 94 that looked new other than an area that covered about 4 inches of bbl. bbl. band and sight base ,looked like some one may have left in in a case and either it rusted or wore the blue off , the ser. # put it as being made around 1979 , after getting all the oil and grease off i used cold blueing on it .The first time it looked bad , so i cleaned it and tried again , it looked the same as the first time so i just kept putting the cold blue on and wiipeing it off , after about 8-10 times ( didn't keep count ) it started to look good so on went the gun oil , next morning it looked pretty bad so off came the oil and more cold blue when it looked nice once more i put 3 & 1 oil on it and it still looks good after about 10 days , you might want to try a few different screws to see how they take cold blue if you decide to use it , good luck !
