As a newbie, help us help you better. Edit your profile to add a signature line that includes at least your first name and home base city/state. When you finally get your coach, add make, model & powertrain to the sig line. By doing so, as we try to answer questions and help you out, we can direct you to local resources, if known. No sense sending you to NJ if you're in WY, for example. Plus, you might just discover another busnut nearby! (Or another busnut might discover that you're nearby!)
Now, to answer your question: PD4106-2732 was delivered new as fleet number 1905 in June of 1964 to The Connecticut Co, HQ'd in New Haven, CT. I have no further ownership info beyond who originally purchased it from GMC.
Oh, and for lots of GMC pics, join the GMC busnuts group on Yahoo. ( http://groups.yahoo.com/group/gmc-busnuts
) There are 244 photo albums for you to look thru! Have fun!!
FWIW & HTH. . .
