Maybe it's a knock off.....Sigren is an anagram of Singer, either that or it was a restoration and the person putting the decals on was dyslexic.....On a serious note, no, I have not seen this brand before....but I am down-under. Will be interested in seeing what the others have to contribute. Interesting.

Looks like a recent Singer clone. The decals just look too brightly colored for me t believe it's vintage.

That cabinet looks like 70's era to me. I vote repro too.

Another vote for recent Singer clone. Probably Indian or Chinese given how loud the decals are. They're still making versions of the Singer 15 today.

I sure doesn't look vintage to me...Wish we could see a closer pic...or into the bobbin case.

I recently bought a 1970's Singer 15 ....heavy as...no serial number, pictographic manual, weighs a ton....may keep it if it can get through some of my utility quilts.

I went to see the lady that had this machine listed. I wasn't interested in this machine but was interested in another one that she had listed. She told me that a person of Russian decent came and purchased it and was so, so happy to find one like that. Maybe that's a clue. I didn't get to see the machine as he had already purchased it.
