Here's a cassette recorder I found on Vinted for only a few £'s
Classic shoebox style
A normal piano style mechanism with pull out handle
Tape transport with mono head and electromagnetic erase head
The bottom of the cassette recorder
Close up of the model label and embossed electric shock warning
Battery compartment
Each side
Front and back
Close up of the sockets and volume control, a DIN plug would be needed to be used with the Spectrum
