It's Standard Pica. Probably a from the J H Shand type foundry, I see them fairly often on Babies.

Like most Hermes Rocket/Baby typewriters, mine no longer had feet on the bottom. You can purchase 3D-printed feet at various places, but I went with the silicone grommet/cap route and found a perfect fit. These are rubber caps meant to replace the cushion on the bottom of certain furniture. The holes on the bottom of the typewriter are 6mm in diameter. These plugs fit tight, provide a slight lift, and a slip-free typing experience. I did have to trim off the tops a bit to fit the body back in, but that's all inside the typewriter when put together. These were a pack of ten for $6 USD (or .60 each).

He gave me a deal on a Hermes 2000 (“The Cadillac of typewriters!”), which featured a knob that adjusted the tension on the keys and the crispest, straightest line of type possible. I’ve since added the 3000, the Baby and the gloriously named Hermes Rocket to my shelves.
