Clockwork winding keys
OK, not sure about the section for this post, but as it relates to a telegraph inker I guess it's kind of vintage telecomms, but this question may be better answered by clock experts...
The clockwork motor needs a key. Do I stand any chance of being able to find one or must I start filing metal... The shaft is square and tapered from about 5.8 to 6.2mm over 19mm length. NB: May be a foreign make (but hard to say). |

Re: Clockwork winding keys
Nothing mentions being for a tapered shaft- but mine is distinctly so.
