I have a few general questions about Mosrites. I am new to this forum, and to the whole Mosrite / vintage guitar world in general. I recently inherited two 67' ish Mosrites, and I am already in love with them.

One of the guitars is a Combo and the other is an original Ventures model. The Combo is with me and the Vetures model is a thousand miles away. The Combo is in great shape. I cleaned it up and I am playing it, very gently I might add. I feel that something of beauty should played and not stuffed in a closet. I would even eventually like to use it on stage, but for right now it's a couch guitar.
First question, should I get insurance for these guitars? I'm not even sure what they are worth but just from browsing ebay it seems like they are not cheap. Who offers this sort of insurance?
Second, I know that refinishing lowers the value of these guitars, but what about touching up? There is a world-class luthier close to me that can do it. Also, the Venture's model is in peices. I want to restore it to playability. Do I need to only buy 1967 vintage parts to stay virtuous or what's the standard there? I know it needs a pickup, which means electrical work. Any advice will help here.
I bought a humidifier for the case. Do I need it? I flew the guitar from the swamps of Chicago to the arid plains of Colorado. I didn't want the the wood to suffer a shock. The guitar was so damp when i got it that the strings were rusting. Strings don't rust out here in Colorado.
What's the deal with truss rod? Is it on the body side? I don't think I will touch it but I want to know.
Thanks for reading. I look forward to being part of the Mosrite club.
