I'm fairly sure yours has a replacement tailpiece, or at least tailpiece cover. The Blue Book of Guitars guide to Gibson serial numbers, which is what Gibson Inc. The Elderly one went for 0, and it was in a lot worse shape! references at its website, lists 80300 as the last serial number of 1924, and 9839 as the last FON of 1918. I paid 0, which seems to be the going rate (from what little previous sales information I could find on e Bay, craigslist, and auction-house sites) for similar instruments in the low-end range of the Gibson MB line.
Has a lot of history with it including and old signature made with a dip pen which I am guessing is from one of its early owners.
It plays great but over all has some wear and tear a bit of rust and oxidation and some mildew spots around the edge from when it must have be stored in a damp environment at some point.
Hi all, I bought an old Gibson mandolin-banjo the other day.
I think it's the MB-JR model, seeing as the hoop diameter is only 9", but it has no model designation anywhere on it.
When traders brought African slaves to America, the slaves brought their own music—and musical instruments—with them. With a body made from a gourd, the banjo was first reported in 1620 by the captain of a ship on the Gambia River.
Structurally, the banjo is very similar to a drum, with an animal skin stretched over a rim.
There is a serial number: 8023-15, but I can't seem to track that down anywhere online either, although some sources identify 8XXX serial numbers in general for Gibson banjos as being of 1925 build.
Other features: 9" hoop, smaller than what is quoted for the numbered MB-# models I've seen around.
Whatever else you see in the [small, from the craigslist listing] attached pics.
