Approx. Value of a Nagant M8 Finnish capture

Just so I can figure out how far I should go with customizing my Nagant M38 Finnish capture can any tell me what the approx. value of one is. It was made in 1941 and has the triangle with an arrow for the factory mark. It also has the SA mark, "D" mark, and several others. There are also a couple of small squares carved into varrious parts of the stock. One square has nothing in it and the others have one, two and three strikes in the square. There is also a second empty square on the left side. They are not really noticable, but if you look at it they are easy to see. None of the serial numbers match. It's a nice gun and if it not worth more about $200 I wont feel to bad about adding my scope, refinishing the stock and metal. If it is worth more I will most likely not touch it. That reminds the finish is on most of the gun is not bad except for the last 3 or so inches of the barrle and buttplate the finish is worn off. The stock has no cracks at all, but to the finish is iffy on some areas of the stock.

Thanks for the help!
