When I invited this I was told it was a "Bert Weedon Zero 1". Bert endorsed these archtop guitars for Boosey & Hawkes between 1959 and 62 before he moved on to Guild.
I was told this but there was no particular evidence of it, no logos or labels, there's not even anything to say it was imported by Boosey & Hawkes, just a small oval mark where a sound-hole label may have been? I have seen a Zero 1 now and whilst that are a few vague similarities, (they are both red), it is certainly not a Zero 1.
Further research led me to the German Vintage Guitar site which had pictures of a 1961 Klira archtop that looked identical apart from having a pick guard. I asked them about it and they confirmed it was a Klira Donella, (or Superio or Montana... ) and that it should have a pick guard so I may get one, one day
