Jim, it is likely that what you called the "Stratton's Patent number" is the serial number. If it is, the Fogg's patent is for the vibrating hairspring stud.

Is there a little steel arm just outside the balance cock to attach the end of the hairspring? It should be pivoted at the back of the balance cock like in this example. Your example will not have the jewel in the upper pivot of the vibrator arm arbor.

Your watch was made in a run of 400 that was begun in September 1864 and completed in February 1865.

Your movement sounds like an AT grade and 140,000 ish and is 15 jewels. Is the case gold or silver, that 13XXX is the case no.? Is there a hallmark or makers name in the case?

Jim, when you are making a reply or post, there is a small toolbar at the top of the window. The rightmost icon is a paperclip. If you click on it, you can upload a single picture that will be linked to your message.

Alternatively, you can send me pictures to post on www.nawcc-info.org (http://www.nawcc-info.org) and I will send you the url so they can be included like my picture above.

Many of these cases in 18K gold have the letters R A inside the covers for Robbins & Appleton.

Not true--there are many case makers and R and A is just one. \

Also, not all were in 18K gold, some examples were assembled in silver.

Now for a real funny one--one confused and misguided collector is even trying to sell a DH and D in a R and A case as ORIGINAL! Ha! (now that is way too early-1854?)
