Poll to decide options for Alps Throwback, which is going to be an Alps-mount PBT dye-sub keycap set made by Signature Plastics in their DCS profile with 1Z (low-sitting) mount.
PLEASE NOTE: while these keycaps are Alps mount for switches, they have Cherry MX mounts for stabilizer inserts, meaning you will need to use Cherry stabilizers (PCB or plate mount) or Costar-style stabilizer inserts. I will have an Alps-compatible PCB available soon that also supports Cherry PCB-mount stabilizers so you could use that with this keycap set.
