I e-mailed this to Gregg before I joined up here but it may have got eaten in a SPAM filter so I'll post this here - hope this is the right etiquette. I think I may have come across a harp guitar maker that I can't see in the Makers Encyclopedia or find by searching the site. I frequent a luthiers forum and someone posted a picture of an old parlour type guitar. I'm fascinated with these instruments and asked him for more detail. The label in it reads:
"Josef Obrecht Instrumentenerzueger Weien, XV. MarzstraBe 31" - a Viennese builder. I did some quick googling and it turned up these links from the sale of a Harp guitar by the same maker:
Plus from the same site a search with the same label details as the parlour but for a different instrument (possibly) than the harp guitar:
Is this a builder you are all aware of?
