Newbie looking for info on Skimmer pictured

[keymaster]

I just purchased a used 70 gallon setup, ton's of equipment, no livestock no rock. Most of the equipment is marked with a mfg but the skimmer isn't. Any idea's what this one might be? Other than "too big for my sump"?:rollface:

Thanks in advance for any help or ideas on how to track it down....

The insignia on top of the skimmer cup means something but I don't know what. At least it's a bump .....

EuroReef (now reef dynamics)...or at least the lid on the collection cup is.

Looks like an older ER 5-3
