I think the O/U frames were sourced from Ernst or Franz Steigleder. If you can find one(O/U or SxS) close to your dimensions, you will be well pleased. For a field gun, sling swivels are very functional but some of the Iver Johnson's by Simson I've handled either didn't have the front eye or it was ground off, which is an atrocity. Simson was large making bicycles and cars and apparently very good at contracts after WWI and the Treaty of Versailles.
But it didn't end very well for the original owners:
"The Nazis made an example of the Simson Company. â ...Wilhelm Gustloff ... was an ardent Swiss Nazi shot dead in Bern by a Jewish student named David Frankfurter on 4 February 1936. To honor Gustloff, the Nazis had given his name to one of the first âAryanizedâ companies of the Reich, in this case a firm formerly owned by the Jews Arthur and Julius Simson. The Simsonsâ company, the Suhler Weapons and Vehicle Works, had received the dubious privilege of being the only Jewish firm to receive contracts from the German army after the Treaty of Versailles. That Jews should be entrusted with defense contracts, of course, enraged the Nazis. The national press had pilloried the Simsons since the 1920s, accusing them of embezzlement and demonizing them as the spearhead of a world Jewish consipracy to emasculate the German armed forces.â --The Business of Genocide, p. 191.
During the war, Gustloff opened a factory at the Buchenwald concentration camp to manufacture carbines, and later machine guns, using slave labor. The Nazis considered this particularly appropriate for a company previously owned by Jews."
Arthur, after signing a document pleading guilty to being the source of depression for the German gun trade, which began with a letter for a group of manufactures from Zella-Mehlis headed by Fritz Walther to Hitler, escaped to Switzerland and immigrated to the US. He died sometime in 1969 in L.A., California.
And some history of what looks to be some sort of forced translation from German can be found here:

I'm chasing the name of a gunsmith or engraver of G. Gueanu(spelling) of Reghin(now Romania) who had some connection to Simson, or possibly Iver Johnson. Reghin had a majority of German Jewish folk, Transylvanian Saxons, from the Sasregen Hasidic Jewish clan. Germans refer to the town as Sachsisch, while the Hungarians called it Szasrengen. There seemed to be many shops there. Can anyone give me any direction?
Kind Regards,
