Can’t believe, Huw, that you recognised it, as initially the pictures do not show needles, so you must have looked at all! That’s dogged determination! Strange that there is no numbering or identification, suggesting that it was made by someone not trained as a locksmith, which would figure as the inventor seemed to cover many different areas, many of not much merit!
Since the key was made first, and then used to orient the needles, which had pointed ends to mark a smoked “receiver”, perhaps each key was filed freehand, so no need for identification.
I imagine that they were made upon an order being received, as part of other manufactures, which is why so few (One) have survived, despite possibly sixteen years of availability.
