Probably an EM1308 as it has the "wide dispersion" face plate. I have those in my three way and they are very natural if used within their limits (800-3800hz for me, coupled to a WO24P-4 at the bottom end and an ET448 at the top).
Not an exemplar if the best execution from the looks. Likely 5th order/30 dB/octave.

I know the coils are not optimally placed, but they are at least at right angles. The placement may not be terrible as long as the coils are not crosstalking and measure fine.
Attached are my notes from the 2023 Axpona audio show. My perspective is a diy speaker builder with more questions than money. I don't spend long in each rooms so take my observations with a grain of salt.
Two years ago, the network for Nostalgia Jr. was a 3rd order circuit. When it was exhibited at Axpona, the network was upgraded to a 5th order circuit. The photo on Facebook is not the current circuit. I will upload a photo of the current circuit. Thank you.
