Here's a rare unlisted (in books/NIA website) porcelain insulator found in Spain. Marked CVM [id=579805650] This is an early pintype insulator made by Closter-Vielsdorf Meuselwitz (one of 4 factories operated by Closter Vielsdorf) circa 1900.

What makes this insulator special is it appears the skirt was made separately from the pinhole/dome and possibly was glazewelded. Crudely made and appears unfinished prior to release from the factory as there is a large gap around the entire inside of the skirt [id=579805934] or possibly the plunger pushed too far causing separation. Never seen this feature before. Glaze is an unusual satin finish. This exact style and size is shown in a circa 1900-10 German insulator supply catalog produced for the Spanish market.

Measures 3 3/4" W x 4" tall. Has inner skirt crack that appears to be glazewelded with no chips! Small spot of wire rub marks on lower skirt. First email gets this rare and unusual porcelain insulator for only $75 plus shipping. Thanks!
