Which Graflex model for this Kodak 6 3/8 f4.5 lensboard

[tom thomas]

Acquired this lens/lensboard combo hopefully to fit one of my Graflex 45 models. Lensboard is wood though and sharp cornered so I suspect it is for an Anniversary or earlier model. Being 6 3/8, I assume it is for 4X5 format. Am I right?

I'm currently in France, lens shipped to home address so I haven't been able to check it out yet. My son says front lens is rubbed but shutter works great. Seller had it listed as Parts since he mentioned something about E-B*y's return policy forced him to describe it that way. Guess sellers' are catching static about descriptions.
