Vaseline (uranium) Glass Triple Cut Glass Inkwell Elkington 1841

Here is an interesting piece that I recently picked up. The holder is marked Elkington with a patent number and date from November 1st, 1841. The vaseline inkwell bottles are cut glass and are made to lock into the base with a half turn which I believe is what the patent was specifically for. I wonder if the glass was made in or about the early 1840's as well.

The metal holder measures 6 1/4" across and 5 1/2" deep and is Marked :

G.R. Elkington
Registered
2 Victoria Chap. 17
No 899
Nov. 1, 1841

The 2 vaseline (uranium) glass bottles measure 2" tall to lid and 1 1/2" across. The large bottle measures 3" tall to top of lid and 1 3/4" across.

I am curious to know if it is likely that the glass dates to the early 1840's or if perhaps this was patented in 1841 but actually produced at a later time.

Any info on this would be appreciated.
