Vintage Blended Glaze Pottery Brush, Stangl, Doug Wyle, and ???

These are recent Flea Market, and Thrift Store Finds! Happy Saint Patrick's Day on Sunday 3/17/2019 :^D
1st is a 1930's Brush Pottery, commonly called Brush/McCoy Pottery 5"t x 6"w Fawn Vase #716 with a Blended Blue and Onyx glaze.
2nd is a Stangl Pottery #3784 Granada Gold Handled Double Apple Dish, that's 10"l x 5 1/2" w x 4"t to the top of the Handle, made from 1959-1978.
3rd is a Doug Wyle Original Clayfish Design, Cobalt Blue, a "Monterey Jade" look blended Green Gray, and the signature White Foam Spots, Whale Tail Serving Tray, or Center Piece, I'm not sure because I've never seen this Piece, only Coffee/Tea Cups, Tea Pots, and other Dishes, and Focus Pieces. The Tray is 21"l x 9 1/2"w x 2 1/2" to the top of the Whale Tail Handle, and is really to heavy to hold with the Tail alone, it could even be a Birdbath! These were sold by Ronnie's Ceramic Co. Inc. and made in San Francisco, Calif.
4th is a small 4 1/2"t x 3 1/2"w with a 2 1/2"w funnel opening Vase, it has a Blended Browns exterior, with a Blended Blues interior, it's similar to a Fulper Pottery Glaze, but is only marked 535 on the bottom, a beauty though, any ideas?

Thank you for looking, all comments, or questions welcome! :^)
