Hi oldguildguy and welcome; If you have pics, you need to open a web-based photo host account; Photobucket ... many others. You can upload your photo(s) to the web host, copy the 'IMG' data (an electronic address), and paste the IMG data directly into your draft post. You will be able to see your pic in the 'Preview' window and if ok, you can Submit your post and your pic will appear embedded in your post. Without a pic, not sure we're going to be of much help.
Speaking for myself, I'm always leary when someone characterizes any vintage guitar or amp as a 'Prototype' without offering some evidence or support for the claim. Assuming, for the sake of the discussion, that it varies significantly from sister models, it could be a 'custom' or one-off version made to special order; that's a lot different from being a 'prototype' but would explain why the model's details don't match similar models. Calling it a prototype also may be concealing the seller's inability or unwillingness to correctly identify the model; the fact that he doesn't know what it is, with all due respect, doesn't automatically mean it's a prototype. Finally, the use of the term 'prototype' is commonly used by sellers to hype the apparent value ... and the asking price.
You might consider asking the seller how he knows it's prototype and, further, of what production model - if any - is it a prototype. Without pics, the description is of no use in determining what model it is or the accuracy of claim.
Edit: Here's a 'test' of sorts to help you decide about the seller's 'prototype' claim. If you ask him how he knows it's a prototype and offers any of these responses:
"That's what the guy I bought it from said..."
"I've never seen one like it and neither has anyone else who's looked at it..."
"Because I say it is..."
Then it's almost a certainty that it isn't a prototype.
Again, welcome to LTG! CJ
