The problem: The seller claims that it is a Firstman Mosrite. Due to my (sometimes annoying) curiosity, I did some research and I ended up asking Mr. Kazy Firstman if he could date the guitar. He says it is not a Firstman Mosrite. This is the thread in the Firstman forum (in japanese, use google translator).

The guitar sounds and looks good. In any case, I want to know what I've purchased (and compile information to demand accountability if necessary).
Any help is welcome!
Thanks in advance.
