A retro 1950s accounting calculator by Adwel in £ Lsd Range: one farthing (1/4d) to £999/19s/11d3/4 Very robust, metal chassis with a heavy plastic cover. Weight roughly 1stone 8oz, or 7kg in foreign decimals ... Complete with ribbon (which needs inking!) uses a 2&3/4" paper roll, as output is solely to paper via internal metal type. Bottom 1d button stuck but dismantling to fix is a job for a skilled typewriter / sewing machine engineer who lives as a hermit. Otherwise it works.
