There are three basic models of Swedish Mausers:
The long M96 (pictured above)
The shorter M38
The very short carbine M94
It looks like you have an M94 stock based on the stock having the short finger grooves. Both the M96 and M38s have longer finger grooves on the stock.
This rifle may be a great shooter and no doubt the craftsmanship on these guns is very good but the day someone put a saw on that stock it killed the collector value.
A garden variety M96 in original condition is worth $300-400 in my experience.
The M94 carbine can be worth hundreds more if in original condition.
If it is in fact an M94 (not sure on the length, years, etc) you are missing the front of the stock, metal nose piece, etc.
As it sits now the value is a shooter, not a collector. Maybe around $200-250.
Here's an original configuration M94 carbine:
Some good info here...might want to measure you barrel...if it is 18" it's looks like an M94. If it's longer, it's probably a cutdown M96 or M38 with possibly an M94 stock (every non M94 I've ever seen has the longer finger grooves on the stock). The fact that it looks like there is some muzzle beyond the front sight makes me think it may be a cut down M38 or M96.
Here's some good info for you:
