Thanks all...great photos and advice as usual.  As butler mentioned, my problem isn't necessarily finding a bolt sleeve, but finding one that matches the other parts appropriately.  I have been studying Krag finishes for almost a year now, and must have looked at over a thousand rifles by now.  Luckily, just when I thought I wouldn't be able to find one, I think I may have done so elsewhere online.  Will only know for sure when it arrives, but as you know it's always a gamble.

Speaking of finishes, I have seen safeties in both blue and white.  What in your opinion, would be the most correct/authentic?
