Please help identify these marks

I am in need of help in identifying the artist and studio (even age or era would be so helpful!)
of a lovely pitcher I purchased recently. I think the first mark may be a PL? The second looks like three loops. Any help is much appreciated!!

Thank you!

Unfortunately I dont know many US Studio potters. Have you checked on The Marks Project website?

Hi! Thanks for responding. I have checked that website to no avail. I am not convinced, however, that this is a piece from the US. I only wish I could get a lead, it is such a nice piece. I am certain it has to be from an established artist.

The top of the jug and position of the handle remind me of Svend Bayer's work but obviously it's not by him. That could mean that it is by a potter, who trained at Wenford Bridge with Michael Cardew, and there are a number working in the States.
