Thanks Connor
For your reply,I agree with you always good to see the marks ,to make correct assessment.
I have managed to get the images of the marks,he was very good about it. (it was only my feeling,that stopped me from asking)
the marks are interesting not sure if these are Hanau marks ,or original early marks?
It looks like the Zwickau mark, The other grape vine mark?does anyone know this mark ?is it the year or maker?

Looks like the owner maybe correct re description of mark. not sure if there is info on grapevine mark?
I have come across an Article in "Handbook to foreign hallmarks" online.
states- Under Heading Zwickau,
The hallmark in the sixteenth and seventeenth centuries was "A swan in a circle .
Only two makers marks are known ,one the intersecting "MW" in ellipse ,the "IS" in circle.
I may be wrong after all it may very well be what he says it is.
