Teapot for ID, possibly Victorian

I purchased this teapot recently, I love the shape and colours, but I have no inkling as to the maker. 3104 is in red and what appears to be an impressed A on the base. It looks to be Victorian/turn of the century, but I could be way off the mark with the age! Google lens image searches and other searches have been unsuccessful in IDing this teapot, curiosity has got the better of me as to who made it!

Any help is appreciated in the identification of this teapot, thanks in advance.

The impressed stamp mark looks like a bell mark and sometimes included with the Bell stamped mark or maybe just flaw. But possibly by  J. & M.P. Bell & Co Scotland.

There is also another Bell Pottery that made crested china and other standard wares. I had a cup saucer once, at first I could see no marks until I looked closer with an eye glass and found a small bell about 2 mm
high x 1 mm wide, could hardly see it.

The example in goddens shows a more rounded bell shape with a loop at the top.
I think it's just simply a letter A. 3104 is probably the pattern code number.
Stylistically I would guess at mid Victorian, probably pre 1880, with some elements
of the Aesthetic movement creeping into the design.

I agree with Denbydump on the impressed mark, it does look like an A, not a bell.

I tried looking/googling the pattern/design code the other week but came up empty, as did an image search on the teapot. I agree with you on this being Victorian, it certainly has a look and feel of it. The lid is not perfect, as the knop has been glued back on, but I couldn't resist it for its shape and style. I think this will remain a mystery.

Thank you to you both for your replies/comments, have a nice weekend.
