Hi, I'm pretty sure this is a WF 8473 Wave Ribbed vase - but I still wouldn't bet my life on it

For a start its condition looks suspiciously good for something that could go back to the 30s and also there appear to be an awful lot of WF lookalikes about - so I'm not taking any chances!
A confirmation would be great.
It's quite thin walled and considering its size - 25.5 cm ( 10 in ) it's quite a 1066 gm lightweight.
Its rim diam is 16.5 cm ( 6.5 in )
If tapped it has a good ring tone
Its colour is a light green - I'm not good on colours - it could be Sea Green.
Thanks for looking

Scott
