I own a 1980 Orion 27 that I purchased about 2 years ago here on the West Coast. What kind of information are you looking for? I have an electronic copy of an old sales brochure I could email to you if you want. If you have general questions, I would be willing to answer to the best of my ability.
Please send me an electonic copy of the sales brochure you have for the Orion 27. Thank you.
