posted the original 1965 version of this portable design with the side handle.
This one appears to have been built in 1974 or maybe 75, model BP3105LR. Made in Taiwan. It must have been one of the last tube B&W sets, only two tubes left amid transistors and ICs. The back cover has the "interlock" warning message, while the bottom of the set has the solid state "no user-servicable parts" message. I believe I've also seen a solid state version of this set. The cabinet can be opened with no tools, the plastic clips that secure the power cord slide off and the back cover can be opened.
Too bad the antenna is broken off, and a chip on the side of the cabinet. Otherwise in OK condition. I bought it at a flea market many years ago.
