1920s VEGA 5- string Open Back -- Is $950 a good price??

http://www.usedvictoria.com/classified-ad/Vintage-Vega-5-String-Banjo_23817843

I'm thinking about having a first look at this old Vega.  I gather they are a pretty good instrument.  But I have no idea of value.  Also, I need to know what "issues" to watch for.

Please help with any advice.

Thanks for reading.
