Much of my internal frame is still there but the outer opening section is missing (you can see someone has just stuck plexiglass over the opening), so this was a very lucky find.
Ron helpfully sent good photos with the tape measure included - so I could be certain we were measuring from the same point.
The rubber seals have perished or are too brittle to re-use. But all the alloy is in really great condition & will clean up nicely. The glass was removed to keep the shipping costs down, and she arrived without any shipping damage.
The only slight glitch was a UK Customs charge ! I should have asked for a value lower than the $90 I paid to be posted on the shipping documents as not only did I have to pay the VAT (@ 22.5%) but also a handling charge... but hey, I'm still very happy to have found one this size.
FYI - UK Customs can charge VAT @ 22.5% on anything valued at over £18 and then import duty on items over £120 - it seems to be a lottery whether they pick out your package but its worth being aware of it.
