I must add this though. A few Dealers and Luthiers have seen this Bass in person and on-line and do not believe the label matches the Bass age-wise. The majority of labels in Violin Family instruments (vintage ones) are false or do not match the instrument.

In this case, the Bilek label was either placed inside to name it or as a repair by Bilek, and the Bass was old already in 1947. Since the label clearly says by translation 'MADE' and the professional that have seen the Bass say 19th century to early 1900's, then it is more than likely that the label itself is real but placed in the Bass to give it a name. Anti-dating though is much more common than post-dating so that remains a mystery to me. Also, it is just possible that the Bass aged quickly since 1947 and just appears to be older.

The answer here is that there is no answer.. Yet!
