By the way, here is what an actual old label from that period would look like. Don't be so easily fooled. When the bass looks half the age of the label, it probably is!
This bass was heavily used professionally until just recently and has 5 different repair labels. Two of them from the 19th century and 3 of them from the early 20th century. Being repaired over and over again wears even the label, especially if they are moved for repairs and then replaced. The 2 old ones shown look to be on old
Vellum, not paper from pulp.
