Another result of a Lockdown Loft Clearance! Belonged to my parents and vaguely remember it as a child in the 1970s. Don't know anything about it really or whether it works or not. So please understand that before buying. There is a no returns policy in operation for this listing. Please feel free to ask any questions and I will endeavour to answer. If anybody has some information on it that they can share with me it would be much appreciated. When I slide a button on the side, the front of the camera drops open and there is a removable cartridge inside. Thanks.
