OK, I'll try to translate it into modern English gun parlance (with my own comments):
Left side:
1 Anson (= boxlock) Drilling 147
Barrel: Boehler steel 65cm
sunken hollow rib like on Holland shotguns (cross section sketch)
Caliber 16 - 16/70 (= 2 "), 9.3x74R (16.8 and 16.3 may be the choke constrictions. Cannot decipher most of the stenciled notes, only read here "???? for altering the rib")
System = action: Anson = boxlock with Greener crossbolt, with selector by means of a small lever // and alternating sear safety (when rifle barrel is selected the right shot barrel sear is blocked and vice versa) // safety slide on tang, single set front trigger, separate extractor (for rifle barrel), without cocking indicator pins
Shaped with large fences like on a shotgun
Master: ??? Weiss January 17, 1939 delivered: February 8 , 39 (actioner?)
(stock dimensions, the original was indeed "English" type without pg and cheekpiece)

extra fine figured wood / additional price

Scope: without
Sights: folding peepsight , and a normal automatic folding sight too instead of scope mount
Sighting: 4.0g special powder and H-jacket bullet with cutting edge and lead point ( this is the contemporary RWS load Nr. 124R with the 16.7g = 258 gr H-jacket at 2600 fps)
Left barrel regulated with Brenneke slugs.
Engraving: Arabesken = scrolls model IV (can not identify the name of the engraver)
(in red:) action body annealed!
