Optics are very clear and are in a really good condition for the age, with what i can describe a bit of chipping of the coating from the inside but that doesn't seem to interfere with the viewing experience. Only real fault on the set is a broken right hand side eye cup which again doesn't interfere with viewing.
Got in touch with a few places to see if they can be serviced and seems like it will be really costly. Around 500AU$ from what I can see.
Anyone had any experience with these before? Are they worth spending such money on them?
I wouldn't mind keeping them as is but if I spend such an amount of money restoring/servicing them, I would like to get some of that money back in case I end up selling them in the future.

Hi Paul,
If you're not already a member of Cloudy Nights (CN) forums, then it might be worth your while to think about joining. Among the many astronomy specific sub forums, there is one dedicated to 'Binoculars'. There are lots of discussions on various vintage binoculars with collectors offering insights and knowledge of not only many different models, but also experience in how to go about cleaning, restoring. adjusting etc.
Of course, the latest and greatest (binoculars) are also included in discussions.
Joe Cali's explanations regarding useful exit pupil sizes relative to ageing is 'generally' true, but there are always exceptions with some older observers claiming near 7mm pupil dilation into their 70's - not me though unfortunately.
Regards,
