There were a few Canadian sets that had AFC as well, a number of the high end Marconi sets did, as did some of the higher end Northern Electric sets. The 37 and 38-3116 sets were largely the same as the U.S models. in terms of big sets I would not turn down a 37-3116 if one came along, but I really like the big RCA and CGE sets from this era, the ones with the motor drive, and a curved dial made of glass slats, I don't know if any of those had AFC or not, but likely, I will have to look at the schematic. As Mike said, one they came out with electrical tuned push buttons they did not really need it anymore for AM sets, the pre war sets with AFC usually used a Foster Sealey discriminator circuit of some kind.
