Elenco Snap Circuits Model SC-300 Electronics Kit. It's missing 2 items. 1 black jumper wire & X1, which is the microphone. You can probably pick the 2 items on ebay. There is one extra connector in the box. Comes with the instructions. Reminds me of the old Radio Shack kits they had back in the day. Build booklets are included.
