A note about Drillings.....
While these were made by a myriad of makers, a few things were in common.
Few were cheap. Cheap German guns had less than three barrels.
Lockworks were as complicated as Sicilian Politics. Oft a Greener style safety on the side of the stock head was combined with a barrel selector on the tang that raised a rear sight(and sometimes a front one also) when the rifle barrel was picked.
Triggers were complex also. Oft the rear of the two triggers could be "Set" to make the front trigger fire with a few oz pull.
Between these features, inletting the head of the stock CORRECTLY requires the expertise of a brain surgeon and the patience of Job.
And oft the rifle portion of these old timers is for an old time cartridge. Various 9.3mm cartridges and the old 25-35 Winchester are common. So is the 30-30.
Sidelocks and boxlocks are both found, and engraving ranges from bad to great.
If I needed to restock a Drilling in order to use it, I;d ask myself some questions.

What do I want to do with this? Most Drillings run a bit heavy for the uplands and are 16 gauge, not the best choice for waterfowling.Weights on the ones I've handled start around 7.5 lbs and go up.
What can I use the rifle barrel for?
Are the chokes too tight for my sports? Many are at least a Mod, and some verge on "Are you kidding?!". And few of these are good candidates for tubes.
Has this been cursed by The Demon of Short Chambers? While some do have 2 3/4" chambers, most are 2.5" and some guns lack enough metal in the right spot to have them redone.
All that aside, plenty of these are carried and shot by happy owners every day.
Were this mine, I might have it done with a game gun style wood set,good pad and made to my dimensions. The 9.3mm cartridges are useful for deer sized game up to elk for the 9/3X74mm and oft camp meals can be made from grouse,etc.
It would not be cheap, but it could be terrific.....
