Thank you Carcano for the article and comments on the rifle. While I was researching Rasch prior to bidding, that rifle appeared in my search results. Along with a similar one auctioned by Holts in July 2022 that was serial numbered 40 above the one you shared (0260 at Holts vs 0220 at germanhuntingguns.com.) Both are quite beautiful!

I haven't decided if I will even attempt finding/fitting a scope yet, but I do know the missing 'wing' will annoy me every time I look at the rifle!
Raimey, I had to look up "Altdeutscher Laubgravur", so thank you for that nugget.
https://www.engravingglossary.com/Hand%20Engraving%20Glossary%20A.htm I visited my local gunsmith to have the stock toe put right. He also had the correct screwdrivers to remove the 2 very tight/reluctant takedown screws holding the action to the trigger guard. I happy to report that there is no rust under the wood line. The stock is incredibly light. Too light actually by my tastes as I'm worried about the thin wood along the barrel line. Some oil staining but nothing to the point of ruining the wood. He is looking at options for re-attaching the missing wing. It appears the cross piece that catches the claws of the scope rings broke. He's looking at removing the rear base to see how complex that part is and if a replacement is feasible. He's a retired engineer and licensed smith who thankfully has taken on some odd work from me -- and he's 3 miles from my house!
