Greypartridge,
You can expect tight chokes. The Rohn is an area in western Germany and some companys have it in their name or their address line.

The Rhon (transliterated to English "Rhoen") is an area of low mountains south of Fulda and north of Bad Kissingen. (For those who've been to Wildflecken, they've been there.) The Rhon is not far, as the crow flies, from Suhl. About 25 or 30 miles I suppose, southwest of Suhl.
English stocked German guns are not common. In my experience the German guns tend to have pistol grips and cheekpieces, but straight grip English style stocks are not unheard of and definitely more desirable to those who do not like the cheek piece stock. It is quite possible it is a restock, but that is really not that important in a shooter. ...
My Simson 12 ga, 35E/70 is English-stocked. Shoots great, carries great.
