Deeper still! Dove into the other WDS references related to ES 2603...

There was a listing of stars from E. Interesting. Could E actually be considered the prime in this system? Correlates very well with the photograph.

Looked at the STF 484 reference, i.e. the Σ 485 G star. Correlates well with the photograph.

Checked the HZG 2 reference. This seems to be the STF 485 N star in SkyTools but that doesn't look right. Based on the J2000 coordinates, I think it is STF 485 I. The WDS says the "K" star here is mag 15.3. Oh. Not seeing that. But if this is all correct, then I can see the J and R stars in the photo. Wow.

And finally, I examined the HLM 3 data. What SkyTools says are the K, L, and D/O stars. Correlates well with the photograph. The "primary" is this situation WDS says is mag 10.4 while the companion M, to the south-west, is mag 11.4. O is the brighter mag 9.4 star to the east. Once again, this data set adds another star to the mix, P! It is the fainter star to the east-south-east, closer to O than L.

Created an aggregate plot (in Excel) for the other stars.

So now I have a couple more...

J is the very faint mag 13.3 star north of I.

The SkyTools K star is a mystery but now there's dim M south-west of L. I'll take it.

P is south-west of O. Dimmer.

R is the very faint star south-south-east of GH.
