Hi, Im wondering if someone (from Opticron?) could then explain to me the difference between 'nitrogen waterproof' which i was told the MM3 60 was via email (date 8th Feb 2016) by Opticron - and which was what made my mind up to make the purchase, and what is now noted in this thread by Opticron staff who say that the MM3 is 'weatherproof' and 'not nitrogen filled' Many thanks

Interestingly, the two US websites I just looked at state that the MM3 is nitrogen-filled, see:
https://www.eagleoptics.com/products...spotting-scope
https://www.bhphotovideo.com/c/produ..._ga_ed_45.html

However websites that I have looked at in the UK simply state that the MM3 is rainproof, as they seem to have simply copied and pasted the text from the Opticron marketing team.

If the MM3 is indeed not nitrogen-filled, Opticron/BHPhoto/Eagle Optics better get their story straight before somebody instructs a lawyer...!

Perhaps (hopefully!!!) there is some simple explanation and this is a misunderstanding, but to me as somebody who's looking at buying a travel scope this year, this seems very confusing and does not instill confidence in the manufacturer's transparency.

Not sure this makes a difference, although lawyers will disagree.
Ordinary air is 80% nitrogen, so as long as the glass is reasonably sealed to keep out moisture, there will be no discernible impact.
I'd actually be much happier if optics still had desiccant ports such as were the norm on military gear. That design accepts that leaks will happen and allows the user to deal with the potential consequences.

Really I think that Opticron should have just replaced Joe's scope with a new MM4. Though obviously with the story out on a public forum they would be wary of the floodgates opening on them to other MM3 purchasers wanting the same.
