Mystery Protein Skimmer - need help.

[Cstar_BC]

I received this protein skimmer when I bought my used tank and in cleaning it I broke a small piece . It also looks like it has some pieces missing and I can't find any discernible brand name on it or model .

It does have a jebao ipx8 Eco pump in it . I think it is reassembled correctly based on the closest Bubble Magnus I could find .

Any idea what brand this is / model ? Was in a 120 gallon tank.

Thank you !
