just thought I'd bore you all with a few tankards - can't remember if any have been posted yet. Don't know if the small indentation at the top of the handle is unique to Davidson, but appears on my examples, and in the book, so cud be a good indicator of origin if all else fails. The green piece (Silver Jubilee of George V) is Sowerby (it carries the peacock's head), but sadly not U. Possibly the poorest quality piece of glass is No. 2 in pic. 2 - which is Ravenhead...very rough and ready. The shorter Midnight piece is an FT 5 - but still no wiser on the other Midnight one, although the handle shape looked a bit 'Wedgwood ish'. The large clear piece in pic. 3 is again Davidson, and was their first design to be registered both in the UK and Australia (1938) - it carries both Nos.............but why doesn't my example show the 'PINT TO RIM' and 'G R', as shown in the book??
