I built a Model 749 in the late 1950's. I am now looking to buy a nice one for my antique radio collection. If you have a Knight Kit Ocean Hopper Model 740 or 749 that you would care to part with, please let me know. I would prefer one that works and is in pretty nice shape, and with a case and a few plug-in coils. I have searched E-Bay, but I have not found one yet. I thought that I would try this forum for a more serious search. You can reach me at my e-mail address or call my cell # at 614-975-0472. Thank you. Dennis Shreve, Westerville, OH
