Psuklinger,
My opinion(only an opinion)that the stock was refinished was based on an overall impression,which included the recoil pad and the somewhat glossy finish.While certainly possible,it rould be unusual to find a 1933 drilling with a glossy stock, showing little wear/damage, unless it was refinished.Keep in mind, this was not a criticism, I believe it is a nice job.A drilling such as this was made to be used, and used frequently. When I lived and hunted in Germany,the Reh(Roe) deer season opened in mid May(1 June in some States).During this time of the year,it got dark very late, which allowed hunting after working a full day(even overtime).I hunted almost every day during this time and very frequently even when it got dark earlier.My experience was closer to a German hunter's(such as would have owned your drilling)than to a typical American hunter's.A drilling such as this one would have been a very fine tool, to be used, rather than an object to be looked at.As such, it would sustain "fair wear and tear"and would show it.Repairing this damage from time to time,adding a recoil pad, mounting a scope,or other changes would be done as necessary w/o any idea that it would hurt the originality.While I know others disagree,in my opinion this is akin to changing the oil or replacing the water pump in your car,and doesn't hurt it.
As far as the L and R stamped on the action,my initial impression was also "left and right", but why? The other parts inside are likely identified as to their intended location, but not with a l or r. Screws, especially "clocked" screws would be marked by lines filed on the unseen end.Typically(although other systems might be used)a screw for the right side would have no mark, one for the left would have one line; in the case of a drilling,a third screw of the same function would have a X.This would only apply to parts that can be installed in more than one location. All that said, I don't know what the L and R mean.
Raimey,
Your computer sees things clearer than mine(or maybe your young eyes), a 9 gram bullet could also be "spitzer".
