1967 Intermark Cipher, Sentinel model guitar. Very good shape, appeared to have not been played in years. I changed out the strings that were very old, and played it, and it plays great, with a unique sound. I know very little about the brand, it is from Jaoan. It's very unique with two flat volume knobs and two tone knobs under the pick guard. It is a bigger size guitar, closer to the size of a Gibson es 335. I found a youtube video of one like it, so you can check that out. Any questions, feel free to ask.
