Beam Expander

A while back I picked up this beam expander, after I purchased it I realized I had no real use for, but I kept hoping one day to have a high power greenie. Well the holidays have come along and soaked up all my money and I need some quick so up for sale is a Melles Briot beam expander.  There are 3 small blemishes in the side as though it was mounted with screws there is also a line of white paint having to do something with the focus.  This is untested and in in know working order because I have no real way to test it (my hand isn't steady enough to keep a laser and adjust the focus) but some testing seems to suggest it is working, but again I am unsure.  Pictures:

Product number

Serial Number

Best offer I see reasonable by the 27th gets it.

I would make an offer but I don't really know what these things go for used.

Well I picked it up for about sixty dollars so I would like to get close to that for it.

What POWER is it ?

you need to get some before and after beam shots!

I can't find any info on it I contacted Melles Griot and they don't seem to have any information on it.

I can try but I have to put a pen laser in it and it wasn't designed for that so I don't know how exactly I would go about doing that.
