Made In Holland Pottery Spinner Ashtray C.F. Mark (Flea Market Find) :^)

Yes I said Flea Market Find! :^D The Flea Market in Concord, California is open again, Face Mask, and Distancing Required! I did feel a little apprehensive, but the Search was on! :^D
I found this on Sunday 6/7/2020, from a seller that was there on Saturday too. The look of it, with the Black and Yellow Hand Painted Glaze Rings down the outside, caught my eye, and Chrome Push Spin Cover, let me know that it was an Ashtray. I couldn't read the script writing on the bottom very well, only the Hand Painted, but not the Made in Holland, that I was able to see after I cleaned, and magnified it a little at Home. After searching, most of the Holland, or Dutch, even German, Spinner Ashtrays, most were Delft Blue, but none of them had the pressed in C.F. bottom Mark, like this one does, and I couldn't find any information about the Mark. The Ashtray is 4 7/8" at the widest, 4" across the top, 3" across the outside of the opening, its 2 1/4" high, and with the adjustable Spin Top on about 4 3/8" tall. To me, this is a piece of Art Pottery, that is also an Ashtray! :^D

Thank you for looking, any information, or comments are welcome! We're almost back to normal, Stay Safe! :^)
