Two Unusual Blue & White Plates

Whilst looking to expand my (embarassingly small !) collection of Delftware, I recently came across these two interesting blue and white plates, the like of which I have never seen before.
They appear to be probably from the same region, but maybe of slightly different periods.

The plate with the reticulated edge measures c.24cm diameter and bears an impressed mark which may possibly be a stylised '7' and '6' combined.
The plate with the lattice edge measures c.20cm. There appears to be an impressed mark, but this may possibly be only a firing flaw.

Has anyone seen similar plates to these and be good enough to suggest the probable country of origin and - if at all possible - the likely period from which they originate ?

Many thanks and best wishes to all !!!!

 

Very sweet!

 

Hi,
I can see the first one with a red or yellow ribbon threaded through it.
