I have an Unertl 24 x 63mm spotting scope of unknown vintage and its in need of cleaning and other service. I was wondering if anyone has any recommendations for service on this unit. Even though its old and the glass is not current it has always had exceptional resolution. I think that makes it worth servicing. Thanks, Rogn

I don't know whether they service spotting scopes, but look up the website for Ironsight, Inc.(I think). They just cleaned and repaired an old scope for me and did good work.

Parsons Scope Service can do this. They specialize in repair of vintage optics.
