old tech

[handrawn]

.

which I was given as a present [second-hand]

it has been given, and still gets, a lot of use - every few years, as today, it needs taking apart and cleaning and piece of sellotape at top left second pic replacing [that is old tech ]

so what is it - not difficult I'm thinking... but bonus points for the make....and the year of manufacture [give or take a couple]
