Anyone who follows the R. Roskell numbers file. will know there are huge gaps, many of the watches he produced, of course, will have been worn out and been ignored, and as the way things are, thrown away, and at the early period no doubt, many would have gone to the bottom of the oceans, or blown away in wars, plus later the scrappers did a lot of damage to antique watches worldwide, sadly it still goes on. By the year 1813/14, Robert Roskell had reached 10,000 watches sold. That for the period was a huge number by any standard. It is my opinion that quite a few of these watches are still with us, though signed by other sponsors. Proving that is not going to be easy, and some people will never agree. Roughly estimated at some 750 watches per year, and all Rack levers. To do that there must have been a large putting-out system, with Liverpool and Prescot, and organised by Roskell. We all know by now that a large workforce was needed to produce a single watch, we also know from the work of others on this board, that these watches were made in batches, but no parts were matching, each watch was individual, which follows each case was individual too. If we look at the watches in the raw, Roskell´s team or workforce would have eventually come to one of the later skills of the watchmaker, the engraver, and he would have engraved the watch before it was gilded. Who told him what he was to engrave. In this case Roskell. Did Roskell put many of these watches aside, and signed for other firms. These and other questions are what I am looking into at the moment if anyone wants to join in, please let me know. This watch is only here as an example of what I am talking about, those with Tobias watches will not be pleased I know but bear with me. I am only saying it could be a Roskell watch. (M.I. Tobias & Co 1811-1880) The number on this watch is 8724 if Roskell it would be 1811/12. It has Patent on the cock, and at that time the patent belonged to Roskell, I could be way out, what do members think. Allan.
