My father owned this Martin Vega banjo that he bought new in 76. Supposedly, it is 10/10 in the world. The back of the body has a butterfly inlay ... 2/10 had a butterfly, while the rest had unicorns. The bell brass tone ring and body both match with the serial code 1795. If anyone has any info, I'd appreciate it as I'd like to fully insure it.
This was the bicentennial banjo from Martin. I'll load some pictures tomorrow.
It sounds like you may have a Martin Vega V45. I have read they only made 22 of them. They had a Mastertone flat head tone ring instead of a Vega Tu-Ba-Phone descendant like the VIP model and VOX of the same era. But I have seen them listed for about $4000 used for sale.
I don't follow Vega banjos closely and must rely on those who do. So I may stand to be corrected here. But in the way of researching one's passion banjo brand, one learns about other brands as well.
If it's gold plated and engraved, with a lovely torch inlaid in the peghead, it's a V-45. The nickel plated version was the V-41. Gruhns has one now on their website if you want to look at their photo to compare to yours.
The bcentennial V-76 had 13 small stars inlaid in the fingerboard for the 13 original states, and very different pot design than the V 41 and 45. Actually a more traditional VEGA pot like a VIP. Quite a bit "plainer" than the 41 and 45.
I am strongly suspecting that the OP has a Galaxy Vega. They always made some fancy ones for the NAMM shows that show up now and then. I have seen a few of these with Martin labels slapped on over the years. It's easy to tell from pictures, however.
