Analog EQ similar to Focusrite 110?

Analog EQ similar to Focusrite 110?

Over the years and after many blind tests, I’ve found my favorite all-around pre is the Focusrite ISA. On top of that, my favorite plugin is consistently the official Focusrite channel strip plugin by Brainworx. There is clearly something about the ISA sound that I like, so I’m looking for an analog eq that is similar in vibe. If it helps, I agree with many of the generalities about the ISA sound: they’re clean, detailed, slightly warm, and have an airy (but still soft somehow) top end.
The first option would be a used 430 or 220 channel strip, but I’m only interested in the EQ right now and I’d prefer something in 500 series if possible.
Does any Focusrite fan out there know of an eq that behaves and sounds similar to the old 110 design? A clone of the high and low shelf would be totally ideal.
