problem is many or most M 88 hunting rifles coming without the maker but having the name of the local gunmaker who sold it. there were two real maker of this rifle C.G.Haenel and V.C. Schilling. In the time when the Suhl Konsortium was making M 88 military rifles Schilling and Haenel were the main contractors who assemble the rifles with parts coming from other smaller firms. when the Mauser 98 became the new rifle the Suhl Konsortium don't get new orders anymore so Haenel and Schilling made hunting rifles with the M 88 action and sold them. Till now there is no clear sign to distinguish a Haenel from a Schilling made rifle if you don't have the name on the gun. I had the idea that the serial numbers by schilling and haenel could be somewhere apart so you can say this must be made by Schilling and this by Haenel but had no time to proof this idea.

and yes, the quality of this rifles is outstanding.
