Goldring Eroica H or LX?

I have a Goldring Eroica cartridge in hand but can't find any marking as to LX or H (high output) model. Is there any indtifying feature? Mine is blck and I have seen blue ones on the net. Is the color diagnostic?
Many Thanks for any help.
I just bought an Eroica H and installed it yesterday using the MM input on my amp. It works fine so is the high output model.

It had no markings as to H or LX. In fact the manual that came with it referred to the Eroica and Eroica LX. I am guessing your unmarked one is the H model assuming the box for the LX indicates in is the LX model.

Only guessing though.
