I almost bid on it but my equally rare 150 F4 Apo N will easily print to my max paper size of 56" rolls and the 150 G is optimized for not less than 50" from a 4x5 neg.
The N is one stop brighter too, it just makes a heck of a lot more sense for murals from 4x5 for me unless doing billboard sized prints in sections.
Had that lens as well. No original box, though, but very clean. That one cost me €100 in 2009, same source as 210 G. Those two, alongside a 105 G ($150 from Latvia in early 2009), paid for a device which shall go unmentioned on an analog forum... the one with acrylic glass cylinders. All three lenses are in North America now. Look for a JML 6 1/2". It's f8, but can be easily modded to open to f5. Not much of a resale value, though.
Sorry for this rant.

I paid $800 for my 150 Apo N in 2013, $300 for my 105 G in the same year and got my 50 G for about $75 in a nice trade deal. Now that I have the room, I might try to source a "Acrylic glass cylinder" but there is no way in hell I would part with the EL's since that is my future bread and butter.
Hopefully the OP finds what he is looking for, these things are getting hoarded and kind of drying up.
Understandably, you're in the right city in the right country on the right continent ("right" as in "good"). In my neck of the woods, that unmentionable acrylic thingamajig and that other device with the spewing action is where the bread and butter is.
