Hi Banjo....welcome to TFF.
There's nothing about either Group Industries or Vector Arms in the Blue Book.
The 2003 Standard Catalog of Firearms has nothing under Group Industries, but there is a mention under Vector Arms:
Vector Arms, Inc., North Salt Lake, UT
This is a semi-automatic, pre-ban Uzi carbine with 18" barrel chambered for the 9mm cartridge. Receiver built by Group Industries of Louisville, KY prior to May, 1986. Reciever fixed parts manufacturing and receiver assembly by Vector Arms. Only 97 of these semi-automatic receivers were manufactured.
NIB - $1300
Exc - $1000

Exc - $900
Hope this helps.
