Sure, Lancaster did produce various "utility grade" guns, I think the company term was "Colonial Quality". I've seen extremely plain, but high quality Lancaster guns, mostly "body action" (this is the term Lancaster used for his proprietary, assisted opening A&D action). I believe there was a time in most English gunmakers history where they were almost forced to make or provide a quality gun minus all the extra embellishments like engraving and extra-quality hand finishing to the shooting public. Most likely they had to do it because the many Birmingham makers were making a mint selling these types of guns, they basically had a monopoly on that part of the market. Makers like Churchill, Watson, Atkin, Lancaster, Evans and many others all had guns made for them to fill this niche so they could be somewhat competitive.
One of Chas. Lancasters "Best" efforts...
