Period Impressions is no longer in operation or printing new stock, so the only patterns to be had are what is left in merchant inventories and second hand circulation. Patterns of Time, Amazon Dry Goods, and James Country Mercantile are good sources. This one in particular is getting harder to find, so if you're interested I recommend snatching it up.
This pattern, which is very similar to the 1735 jacket featured in Janet Arnold's Patterns of Fashion, has been around for over 20 years, but I have found precious little about it online. Few people seem to have made it, or if they did they didn't put much about it online. I recently bought it in the pattern set 12-14-16.
