CC or RC mark? - Little Shino Tea Bowl

Hi, Can anyone help at all I'm trying to identify this lovely little Tea bowl - The Mark Looks a bit like rc (but i cold be mistaken)...









Any help very much appreciated... It's a shame such a brilliant little pot, would love to find out more

Very nice, but I don't recognise the mark. Would you mind if I shared it in a tea bowl collector's group? Someone might recognise the mark; might even be from the US

I would appreciate it very much if you could Naomi - The more exposure the better, it's so difficult with so many potters out there. Thanks

I'll report back if I get an answer. Looks like a bit of carbon trapping on the shino which points to woodfiring which is more popular in the US
