Hello John,
I did have a close look at a 'Brummie' Tempest for sale at the Imperial to see if it was that much better made than the current Turkish model. To be honest, the bits that could be seen didn't look to be made that much better to me apart from the area around the breech seal which was a far better arrangement on the original than on the Turkish version.
Still, I must speak as I find and although it will never have the place in my affections that the all steel Webley pistols do, the Turkish Tempest is not all that bad and as I said I can't say I don't enjoy shooting it.
Regards
Brian
