Mystery JT mark, Fri

Hi I have some of this potter's work, came here looking to see if there was any further info on them. Some have incised marks and are dated late 60s, others have this impress mark and one little owl that looks to have been an end of day/week piece has a painted 'JT' mark with Fri underneath. That's actually to hand as I collect owls and its on display, the rest is currently boxed. I can upload some photos if they'd be of interest, I know this potter's work has cropped up intermittently on the British & Irish Studio Pottery Mystery Pots group on Facebook from time to time, it would be lovely to get a confirmed ID at some point!

I've just been through my Google Photos to collate an album or the rest of the pieces I still have (barring the large teapot which sold at a fair). They are nice pieces and I'd really love to find out who made them. Here's hoping

The owl is a student piece. Students often write the day on the base so the technician knows when to fire them. It implies the job lot you own constitutes a lifetime of work for this potter. Possibly a hobby potter who only occasionally sold their work or gave it away to friends

I’ve split the thread for the time being

Websites are often impermanent so I've add some of your photos to your opening post. There are various firing flaws so I think a student who became a hobby potter is most likely. Possibly living local to where you found them. Job lots like this are often found at auction or in charity shops when the family are having a clear-out of a deceased relative's property
