Aria electric guitar information request

I am hoping that someone might be able to help me to identify an old Aria (not Pro 2) solid body electric guitar. I bought it second hand in about 1981 and believe that it actually dates from the mid 1970s. I have searched the Aria archive but cannot find a guitar like mine listed.
The body is symmetrical, the colour is a kind of burnt burgundy, it was made in Japan and carries a serial number 062370.It has two pick ups, and, unusually it has no scratch plate.
Any information or advice would be greatly appreciated.

Many thanks.
