Set of three vintage Perkins rotary brass & porcelain switches

Description

Set of three vintage Perkins rotary brass & porcelain switches. Looks like someone started cleaning the switch on the right so some scratching. I’ve left them as found unpolished with some old paint residue and dirt. That switch also has a nick on the porcelain tab that doesn’t seem to affect it at all. Small ding on the one with the on/off window in the last picture. Please see pictures and consider part of the description. All dials turn and click fine.
