Info on what this might cost?

[Ace Lungger]

 :)I found the Rolling Block action 1887 Swede, has a new barrel head spacing is done, needs changed from rim fire to center fire, it comes with the extractor but it isn't installed. I was hopeing, that I could get a close guess of what a gunsmith would charge me to do this? I play with simple stuff, and i might be able to install the extractor, but I would rather take it to gunsmith and have it done right!

I would be great full for any and all help!

Move firing pin, $80-$100. Fit extractor, $40-$60 . This is what I would charge in my shop, don't know what others would charge.
