Like Larry mentioned..
a early WW2, or earlier, made by Mauser, DWM,etc. are great. Czeck VZ24 are great. Mauser "Standard Modelle" (spelling?), a non military version, would be great. A post WW2 F.N. (Belgium) would be great, although most are already "sporterized" ( drilled and tapped for scope, low-safety, etc ). You'll want to get a "large-ring" '98.
Probably first thing to do, is get a copy of the book " Bolt Action Rifles" by Frank Dehass. Much very good info in there. He also brings up the subject of the cut-away in the side of the reciever wall, for loading from stripper clips..on one hand, it somewhat weakens the reciever, on the other hand, it allows vented gas ( in event of ruptured primer ) to escape.
Or, if you are going to load the .257 Roberts to only factory levels ( not plus-P ), one of the '95's ( preferably German made ), or a Swedish '94/96/38 would work fine. I have a DWM '95 reciever ( no thumb-cut ), with Spanish '95 bottom metal ( hinged floorplate ), and a mint '94 barrel ( 6.5X55 ) that will be my next project, but alas I don't have the skills you have, mine will have to be done by a 'smith.
