This elusive radio is among the very rarest early pocket transistor radios extant... Due its rarity and its classic and iconic period styling, it's highly sought after by collectors... The highly desirable Realtone TR-666 "Pioneer" is exceptionally rare in working condition, and even rarer in all-original working condition... The piece is in original mint condition, and is a real powerhouse receiver... It easily pulls in several local stations loud and clear... It also has its original earphone (works great) in its original plastic storage case, and its leather carry case, both in excellent condition…  Notice to potential buyers;  I currently have two open non-eBay offers under consideration... If you want to purchase it (at my ask), please message me first to ensure this radio is still available...  If you're making an offer and its already sold, I'll just decline your offer and reply therein... So, it's easier if you just make offers...
