I think it's more likely that Feast raised Setigera X Noisette seedlings beyond just 'Baltimore Belle', but that's the only one which survived with its name intact. Looking at the other Setigera Ramblers attributed to Feast, one can see others released which were also described as being "incarnate" -- to me that reads as "shades like those of old non-Tea Noisettes".

The other thing is that while the blooms look very similar, 'Baltimore Belle' isn't quite as "viciously vigorous" as "Arcata Pink Globe" / "Moser House Shed Rose" -- at least from what I've read. I don't grow both, just BB. From what I've read, "the pink one" couldn't be trained into the tree like I've done with BB because "the pink one" is too shrubby and dense at the base. But I'll have both at the cemetery eventually, so I'll be able to compare that myself.

I still think they're two different roses, but most likely full-siblings. Maybe even from the same hip.
