Here's the batter head logo from the Pork Pie bubinga/cherry snare that I purchased this past week. Has "Head made by Remo USA" in small print at the bottom. Maybe it has something to do with the line directly above it.
I couldn't find any info on the Pork Pie web site. Just that Remo heads are supplied. I'm guessing that since its a single-ply coated head it's an Ambassador. Ditto for the clear snare-side resonant head. My guess is that if Pork Pie wanted a couple thousand Ambassadors with the Pork Pie logo, Remo would be more than happy to comply.
Anyway, I'm going on the assumption that it's an Ambassador. It's been a few years since I bought one. I've been using Evans and Aquarians for a time. I hope that the coating lasts a little longer this time.
