They seem to run about the same as any M44 in price.
and there are a ton of good condition M44's out there for sale ranging from $150.00 to about $225.00 and most include all their accessories!
In the condition you describe it and without actually seeing it for myself, its kind of hard to say for sure but as it is missing stuff and has pits in the barrel, I would probably offer $100.00 to $125.00 for it and go from there.
It will all depend on how bad you want that particular one though, personally, I would probably not go over $100.00 if I was looking at it as just a shooter!
I paid $225.00 shipped for my M44 from a collector, but my reason was because it had a perfect, like it had never been fired barrel but had a few dings in the stock, I wanted it for a shooter and not a wall hanger!
