Trying again to post photo [img size=360]https://kovels.com/media/kunena/attachments/legacy/images/2013_07_31_14.jpg[/img]

I have two matching glass footed inkwells, which I purchased in an antique shop in England. One is marked with a stylized H over a C (or G). Does anyone know the meaning of this mark? I have included photos. Thank you for any information that you can provide.
