Nothing yet.
I wouldn't give up hope though. Sometimes folks get busy and it takes a bit of time for the "right" member to drop by.
Meantime, all I can do is reiterate that this is likely pre-1980. The serial number LW350RBS is a clue but interpreting it is problematic when made before the Matsumoku era. Here's some information from the AriaGuitars.com archive page:

Dating Aria Guitars
Dating Aria guitars is a mix of fair precision and historical triangulation. The early guitars did not contain serial numbers, so you have to go by the rough historical outlines here. There are no pot codes. In the mid-'70s serial numbers began to be used. At least for Aria guitars made by Matsumoku, the serial number contains the year of manufacture in the first one or two digits (Y##### or YY####). Thus, a guitar from 1979 might begin with 79####. One from 1981 might begin with 1#####. The scheme becomes less sure after 1987. Some Korean- made guitars use a serial number with year and week indicated in the first four digits (YYWW####). Thus 9628#### would be from the 28th week of 1996. However, this is not the case on all guitars, and some have serial numbers which are not date-coded.
Based on this information it doesn't look to be a Mats guitar. But even Aria's own archives are sketchy at best. If you check this page you get an idea about the LW model line but nothing specifically relating to yours. These are all Mats and later references:
http://www.ariaguitars.com/int/00int_main/archives_acgtr01.htmlWe can assume from this that the
L is simply the model line designation, which also includes 12 stringed models.
W probably stands for
Western as in "Country and Western".
RSB was used in the Mats era as a designation for their
Rock Solid Bass line, but
RBS may just be a reference to the finish.
Hope this helps, a little.
