Stoneware vase with incised JMR mark.

A drip glazed vase, stoneware, with an incised mark, JMR.
Any help with ID appreciated.

Haha, thanks Naomi.
I shouldn't have bought it to be fair. I only picked it up out of curiosity because of the glaze. I put it down, mainly because of its clunky bottom, then was told (as I was walking away) that I could have it for a pound.
I try to stop doing this (as I've too many pots as it is and am trying to focus more on quality and bits I'm happy displaying for a while at least), but couldn't help myself
On the plus side, I must have left a good 15+ pieces at the boot sale, so I'm getting there, I think !!!

I know exactly what you mean. The problem, in my experience, with continually picking bits up is room.
I bought solidly for 15 years and still have stuff boxed up I haven't seen for eons. I haven't the room to do what I used to and I'm not paying for storage anymore, so less buying, being selective, and feeding pieces into the local auction, along with eBay, is helping me get on top of things, I think!!!
I could have come back with a car full today, left some lovely bits.
A trader I know, lovely person, was selling an old twin handled Upchurch vase for £20, it was worth £80 to £120 all day long. I advised her to stick it in auction.
So much pottery for sale, so cheap, so hard not to buy it 🥴

That's a good tip, ref photos. I'll photograph something at auction from time to time.
I used to carry the old bible (Yates Owen) in the car everywhere I went.
Spent more time in charity shops down the years than is normal haha.
I try to be a bit more discerning nowadays, have to be. I obviously don't have a fraction of your knowledge and experience, but I have more confidence in my judgement than I used to.

That makes sense, I am relatively new I think (compared to many of you on here) in terms of studio. It used to be all Moorcroft and Beswick, once upon a time. Cobridge stoneware was the start of things changing in terms of my tastes in decorative items.

I agree, Museums are such a tease.
The one in York has some amazing pieces, but it is awful not being able to touch something. Still, I do like to wander round it every few months.
