Vintage Record-A-Call Telephone Receiver & Conversation Recorder Handset HR-100

Super cool vintage little spy piece for collecting evidence, lol jk. You will need a micro cassette tape, and cord. All compartments are clean. Normal surface marks from age and storage, but in overall great condition. I put batteri es in it and it turns on, but not sure how to test it further without a cassette and phone line. Will not include batter ies. This item is being sold in 'as in' condition. "Record-A-Call HR-100 Telephone Receiver-Recorder is a must-have for anyone interested in dictation and stenography. The handheld device is perfect for recording meetings, interviews, or any other audio activity. It uses microcassette recording media and is ideal for office equipment, business, and industrial use." See pic for measurement. Thanks for looking and feel free to ask questions or make an offer.
