My FN 98 will be transformed into a close up rifle in the mighty 500 Jeffrey aka .Funfhundred Shuler.

in fact the metric designation of the original, from which the 500 jeffery was a copy, is 12,7x70 Schueler.
its a development from August Schueler, gunmaker in Suhl. This family still exist there but nobody work now as a gunmaker so what I know.
Krauts write this name with a umlaut.
