The problem is that Canadian Vet's usually brought back pistols/handguns and not long rifles. At the end of the war there was a US order allowing troops to bring home war trophies, many of which were long rifles (K98's, shotguns, drillings etc.).
As a result you have several nice all matching long rifles in the US and several nice all matching P08's and P38's in Canada. Most K98's in Canada were post war imports and were more than likely messed with by either the Russians, Czech's, importer or bubba.
An all matching K98 in Canada would run $800-2500
Norway/Czech Refurb or German bolt m/m $400-850
RC or m/m $350-600
Values on K98's are determined by condition, matching parts and maker or other significant markings (unit, luftwaffe, SS, etc.).
VZ24's were very close to a K98 and many parts were interchaneable. They were used by Eastern Allies of Germany and by German units, especially the SS who were in direct competition for arms agains the Wehrmacht. The most valuable VZ24's are the G24(t) rifles which were aresenal re-furbished by the Germans to look like a K98 (Stock disc incerted etc.).
G33/40's are not rare in the US, but do get premium prices $1200-3000 which are similar to US G/K43 prices.
In Canada most G33/40's I have seen run for $2000-3000 (Wolverine Supplies has one listed). I think they have a premium price because they were used by elite mountain units, including SS units.
I recently bought one for $1200 (bolt m/m) and end of the day once I import it from the US and get a G33/40 bolt, I will be looking at $1500.
RC's are great rifles if you want a K98. German made, all german parts, many are not peened and retain all markings. Several mysteries have been solved by obtaining RC reciever and barrel codes.
Czech/Norway rifles are a step up, usually have more matching parts and retain original finish.
