I never do this but this is too good to pass up (note this is NOT my auction nor am I affiliated in any way with the seller):

Not because of being a classicist-wannabe, but an old book fan, I’ve known the existence of this volume and have never seen one offered at less than US$100 (it is rebound which may account for the difference). Perhaps a fellow textkit-er with the spendable cash can get this and make it one of our off-the-beaten-path resources? 
A Glossarium Sanscritum is also floating out there, but I digress…
Best,
