Old Victorian Fairy Glass Christmas Lights with Pontil mark

[geofrac]

I found these some years ago at an thrift store and I bought about seven pieces. There are two designs: one with a crude lip and a pontil mark, while the other has no pontil mark and looks like a typical Victorian Fairy light. Attached are a few pictures. One is a rust color and the other is light blue milk glass, these have a glass or sand pontil mark and are pictured next to the other typical fairly light without the pontil mark.

My question is: Does anyone know anything about the two with the pontil marks. They appear crude and look old. I cannot find anything on the web.

Thanks for looking
