Yep, agree.

As long as it doesn't have a burnt out barrel, I'd buy it.

1. How much does the scope being drilled into the action hurt it?

Maybe that's why it's priced at $2000. Yes, it hurts it from a collectors point of view but as an owner / shooter, no. Also means you can scope it with a scope you like without going through any pain of butchering an original rifle !!! LOL

2. Does being a sporterized service rifle make it that much less valuable than a commercial rifle?

Not sure.

3. Does the Nazi proofmark along with the Westley marks make a difference?

Not sure but sure makes the rifle interesting IMHO.

4. Are those the original service sights?

I don't think so BUT I can't see them that well and as with any rifle, they made what the customer asked for.

Would have to compare against other photos.
