CHP T&C

I posted this in the previous CHP thread but since it was posted to page 3 in the thread and that thread was 6-7 years old I thought I would start a new thread on this board to make viewing the pics easier. Im sorry for posting twice. 

If anyone can help me out with this one I would appreciate it. I cant seem to find any info on this board. I’m confused because the board has the CHP logo, a modified LB looing logo and the T&C logo on it. It dose not fall in line with the serial numbering system that appears on the majority of T&C’s. It looks like there are the initals GT on the deck by the leash plug and EM on the bottom. I purchased the board from the former owner of Rockys Surf City in California via Ebay. Appreciate the help in advance. Thank you. Board is 5’9"
