A rare and vintage Sinclair Calculator kit in perfect unused NOS condition.

Includes all parts, paperwork (receipt, instructions, construction, replacement parts order) and is the best from my late fathers collection.

It is from 1977 as shown on the original postage label.

All parts are supplied in the kit and are unused. I have taken out the original pack of batteries as obviously these have now leaked and I don’t think these should be sent through the post. (The leakage is internal to the battery package and has not escaped) The picture shows the battery type needed to power the calculator but will NOT be supplied.
