Help with Vase Shape number please. It's 667 or 2070.

I'm 99.9% sure it's C/Lynn, but the base information is completely covered with the glaze.  I can just about make out that there are some numbers, but that's about it.

It's pure white, so sorry about the quality of the photo; and measures approx. 25 cms. tall.  There are 'potting rings' inside so I'm assuming it's hand potted!  There are also a few feint vertical lines from perhaps a mold.  I'm really not sure.  Any information would be really appreciated, and also an approximate - even ball park - idea of value.  Many thanks.

Hi hazlette
That is a slip cast vase and the old number is 667.
It also has a four digit number .... 2070.
I saw one sell not too long ago for over $100
Must have been a bidding war going on ........?

Thanks Ev. Really appreciated. I'm thinking of putting it up for auction sometime, but I had no idea of where to pitch the value.

Wow. I'll have to put in a request for a bidding war too if that's what price was realised. Thankyou again

Congratulations on your last minute bidding war hazlette

Thankyou Ev. These bidding wars don't happen too often; well, to me they don't lol. I was delighted; and it's gone to a very good home too. And ..... thankyou again for your help.
