Old pottery with writing on back

[Mthompson]

I found this piece of glass with partial writing on it amongst lots of other pieces that would have been part of it. Land is in southern Arizona with an old foundation dating back to early 1900. I can’t find anything online with this little amount of writing. Do any of you have any idea?

I can't help you but I will not be at all surprised if someone is able to glean additional information from the limited information on the piece.

A possibility. This is dated to 1870-82.
