Flambe Glazed Frog Teapot - Mark?

[tipton444]

Hello friends,

Can someone tell me what the mark is on the bottom of this lovely teapot?  It is very well made and it came out of a wealthy New England estate.  Thanks for all the help!

It says Bo Yun Quality Product...Bo Yun seems to be connected to Shiwan ceramic kiln.

Thank you very much Peter.  I can't seem to find any information on "Bo Yun Quality Product," can you find anything?  That's great that it may be connected to the Shiwan kiln, any idea how old it may be?  I'm guessing it is not that old, but then again I've seen items marked "Precious Product" as 1920 and 1940 so what do you think?

Also, is it the same or different from "Bo Yun Tao Fang?"

Tao Fang means just "pottery studio", Bo Yun is its name. So it should be the same, just a slightly different mark. No idea about the age, but fairly recent judging by its glaze. There is not much information on such items in Chinese either.
