Need help with an early bottle pulled out of a river!!!

[PlaneDiggerCam]

This bottle was pulled out of a riverside dump which yielded 1870s bottles and broken pontils. This bottle was hard to photograph because it has river stain and I haven't cleaned it off yet. It has a deep intention on the base which I had thought could be a pontil when I found it, but I guess not? Can anyone give me a date range and confirm whether this is a pontilled bottle or not? The bottle is also ice aqua (hard to see) and has an odd embossed H on the back top right corner.

Thanks,

An 1890 - 1910 bottle. Soak it in a laundry bleach solution, and photograph it agoin. (By the 1870s, American glasshouses were using a snapcase, not a pontil rod.)
