The original sales receipt is from John Wanamaker, February 1911.

My own L-door Victrola XVI, also from 1911, has the triangular opening in the needle chuck. Perhaps the C-series ushered in this change? Yours is a B overstamped as a C, mine is serial number 37788 C. Mine still has the bullet brake, the round speed indicator has the 78/80 speed markings (earlier versions were stamped 76/80, IIRC). Mine came with a full set of the albums with the 17 numbered sleeves in each, versus the record boxes (which I'd much prefer any day).
Mine also came with what----I assume---is the original receipt. The clerk in 1911 evidently felt that the barest minimum of information was sufficient. We only have the customer's name, and for address it merely notes "City". The receipt is from the Cincinnati branch of the Rudolph Wurlitzer Co., is hand-dated July 20, 1911, and notes the sum of $222.40 "to merchandise" was paid July 19,1911 (date in the inkstamp, with clerk's initials). Were it not for the fact that this receipt was carefully tucked into the drawer with the record catalogs and ephemera, and the bright brassy "Wurlitzer" tag inside the lid, it would be easy to dismiss this receipt as just a scrap used as a bookmark in the Red Seal catalog.
I got this Victrola in Washington DC about 20 years ago, it came from a local auction house that liquidates estates. This Victrola still has the inventory tag tied to the speaker door from a DC moving and storage company where it (evidently) sat in covered storage for decades. The address on the tag lists the old address of the downtown storage facility, which was a massive fortress-like building and was replaced in 1965 by the Washington Post offices. This is the second L-door Victrola I have owned. My first one, which was "brought back from the dead", I sold to a collector friend who never paid me for it. Still---good things come to he who waits, I am delighted to now own this gorgeous, pristine Victrola.
