I had the following email from Heidi Nakayama
Even though the mystery shuttle looks very similar to the Parker patent, the Parker shuttle was made of bone and the 1868 patent date makes its years apart. Jane, I would suggest to the shuttle owner to visit the US Patent website:
Look for the “Issued Patents” box. Click on “Patent Number Search”. Enter 1,173,102
Click on “Images” to see full description.
The Dill Shuttle is the closest match to this shuttle. The application was filed in 1914 and the patent approved in 1916. There’s a possibility they put 1915 on the shuttle because they thought it would be approved by 1915. The best thing to do is read the description and look at the shuttle to see what similarities there are. There's also a possibility that the mark "Patd 1915" was put on the shuttle to discourage copies or it could be an English patent.
Enjoy researching this, please let me know what the shuttle owner thinks after reading the patent.

Another message on HBT from Sharren also suggested looking in Heidi's book. See following.
It looks very similar except the bobbin on the shuttle above is wound using a key. Her dad might have adapted it for her, or it might be something new.
Is there a UK patent office? It might be worth calling them or if they are online, looking through the site.
Jeannette wrote this too
Another suggestion was that there may be a hole in the shuttle for a crank. The owner says this isn't so as there's no sign of a hole.
I will add any further information to this blog if any comes in. I tried accessing the patent site but the images wouldn't show up for me. What a nuisance!!!
