    This is just a stray memory trace - of the paradoxical kind that doesn't
    go away, though essentially valueless.
    I was in a Midlands  supplier's store - probably in Birmingham (UK)
    and I was looking over the amazing variety of cast brassware
    (of the kind which was advertized as 'toys') and I saw a taffrail log
    hanging on a wall - for sale, new - several minidials and pointers
      (for distance run?) and a speed indicator.
    
    Could Walker have been a Midlands company?
    Did it expire in the last twenty years or so?
