Good luck in getting your hands on a Finnish Capture SVT-40. They are like hens teeth in Canada. Your biggest challenges are going to be finding one for sale. The next biggest challenge will be getting it for a reasonable price. Some above have listed previous selling prices, but I could see one going for higher as there is a extremely limited supply and a lot higher demand.
In regards to the plumb bolts and electro-penciled parts are often debated. Some say the later production SVT-40s had plumb bolts, others say it was only refurbished rifles. Part of the issue is there isn't a lot of people alive that have used these rifles before they were refurbished and those that did tend not to speak English. Another big issue with getting information on the original configuration is that since so many were refurbished only the Finnish ones seem to have escaped it and even then they mixed up parts (as since they didn't produce the rifles they had to strip some for parts for the others). This leaves a very small pool of rifles to analyse to try to glean information from (made smaller by Globeco). I am not sure about the electro-penciling but some countries at the time used it for some of their parts as it was easier than stamping (the Swedish AG-42b comes to mind). Remember that the information can change look at the triangle '2' on the SKS where people thought it was a East-German used one (turned out just to be a marking to determine where it was refurbished).
Hope this helps.
