From portugal but by who?

I have drawn a blank once again with this vase
It has a lovely glaze
Always glad of your collective help

There's a lot of it around. It's copying museum pieces, so I assume they were sold in museum shops and tourist shops. Likely to be several potters in a particular region rather than one manufacturer

The nearest I got was ALCOBAÇA where there, as you say, several artisans work together
Its just if thats hand painted as it says its very good
Well done EA who ever you are
thanks NaomM

The date refers to the date of the original pot they've copied
SEI = Secolo
I XVII = 17thC
EA or ER = possibly AD or era or century

Another puzzel for me unravelled
I had worked out XV11(no idea how that fitted in )
SE1 i had no idea
And EA I was miles away
I will enjoy it for a short while now I know a little more

Some of the Berardos pottery is also marked Coimbra, but I couldn't find any company information.

Thanks for taking the time to reply Every scrap of information helps the search

There is a large pottery in Coimbra, Ceramics de Coimbra and when searching that I found nearly all the pieces (etsy pic click etc) all had SEC XV11 underneath
Which could well mean the design was sourced from then, as NaomiM said but
always on the last line was a diffrent name/ inital
Could this be the decorator?
