I am looking for lens specifications for British telescopes, specifically the Tel Sig series and the sct. reg. MkII, would any one happen to have a source?

did you ever find a source for the lens
Bit of an older thread and strange no one answered at all. Even though he has lots on his plate most of the time, member Warren may have a source or even the spec you ask for. Worth a PM to him, be patient looking for answers.
