Green vase painted A, incised J please help ID

Hope someone can help as I have been trying to ID this for a month now.
I'm thinking it must be homemade..?
I love the green colour.











THANKS

Looks like you've stuck a photo in the middle of another photo so they're not opening. Can you edit it?

I think I have sorted the images but I can't ID it.

To me the marks look like glaze and clay body testing marks used by potters to test how different glaze mixtures and different stoneware bodies work when fired.

Thanks Studio for sorting it out, I tried but afraid I'm hopeless with tech' things.

By the way Naomi your pinterest page is great, I've ID a few pots of mine with the help of your pins.

Alas all the painted A's you have don't look like mine : (

ps, Studio thanks for your thoughts on the vase.

I'm thinking same as sp , looks like a number 4 suggesting test piece.

Thanks Ed, I appreciate your help.

I think I'm buying a lot of test pieces : (

Glad it helped.   

They really do help though I'm often going back because I've got a memory like a sieve.

I'm going to copy all of them in a little book in alphabetical order.

Cheers : )

Better make that a BIG book
