I would appreciate help with this. I think it is a multipart, glazewelded but do not have enough experience to know for sure. I believe it is glazewelded because the glazed top of the pin-hole is partially broken through and I can see the white glaze of the top part. When I look at the piece around the lower skirt, it just appears to be glazed. Anyone seen one like this? Size is 5.75"d x 3.75"h

Update: Consensus is this is a glazeweld, U-957. Thank you all for your help!
