npub14vgamf2zucjlrxrp9tuudutklyt9ny8at3g5t6d4z7zs22g7gjqsujasrr (npub14vg…asrr) No mechanical calculator in my loft - must have given it away earlier and forgotten. Closest I could find is these: modern chinese abacus and 1950s slide rule I used at school (wasn't new then). If you want either I can post!
