I've got a really old Adler typewriter that my mum gave me years ago. I used to use it in the late 80's before PC's and microsoft word became the norm. It must be well over 40 years old. I haven't taken it out of the cupboard to see the specific model, but on the top it says 'Special'. Weighs a ton! It still works I think, and is grey coloured. Wondering if it's worth anything much to a collector.
