Here is a link with a little info. It is referring to Simson and Frey. No “p” in Simson. Not sure if that will help with your search.

In short,  in NY NY. Someone from Germany, Heinrich(?) Roth, came to NY to manage their violin dept. He and another guy, mid 1930(?), bought the company. It later moved to Cleveland and, either from this link or and other site, it was bought by a company in Cleveland.. 

Roth joined Simson and Frey in 1922. There is more info in the UK forum link above.

I am going to look for more info after I finish my coffee. Interestingly, have not found any with odd accessories.

Irv, you always find such interesting things. 

ADDENDUM

I edited this post twice. I had added a link that I thought would get Irv info. Upon further looking, it really was not going to get him anywhere. So, I edited it again and removed the link. Mentioned in case someone read this earlier and wondered where the link went. 

@Irv, Silly me. I clicked my link in my post above. Link is good and takes you to that business card type old ad. There is a tiny magnifying glass in the upper left corner of the site, sort of, that you can use to enlarge the text. I might download that Google reader on my old Galaxy and download this. Might be interesting. You need a magnifying glass to see the magnifying glass with an iphone.

It does seem to be just information, not auctions, etc like eBay.
