Need help with ID

[Storer50]

I just game back from some local antique malls after spending $25 bucks on a few items. Picked up 3 Gillete Safety razors. I think the nickel razor in the middle is an Aristocrat Jr. I believe the 2 brass razors are the same model, just different handles. Can anyone help ID? thanks

Tech, Tech and Tech. Middle is a fat handled Tech, the other two ball end. Are there any date codes on them? (Single letter underside of head on left, number on right). If not, what shape are the slots? (A date range will be known based on the slots if no date codes are present).

ETA: Is the handle on the left fluted?

I don't see any date codes. Yes one of the handles is fluted.

Both brass razors have rather this almost rectangular slots. The nickel fat handle has wider slots.
