Meissen Blank Mark? Turquoise Tureen with Italian Capodimonte Style Relief Flowers

Hi.

This my first post here, a wonderful site you have I'm very surprised I've only just stumbled across it.

I have an interesting piece that I'm trying to identify. It’s a turquoise tureen with birds and relief flowers which look rather Capodimonte style to me. But then on the base it has a blue Meissen mark with an extra blue line through the middle? I’m not sure if this is perhaps a Meissen blank mark or not? But other Meissen blank marks I have seen seem to have a white marks through them, not another blue one.

It’s also imprinted on the bottom JC with 22 underneath (the 22 is followed by a squiggle that could be a 5 or S but doesn’t look like it really is), the imprint is too feint for me to pick up in a photo though.

On the inside of the base and the lid there is three black lines, likely to indicate which way around the lid goes.

Any information to help identify this piece would be very helpful, thank you :)
