Question on Parker SBT

[Tom Dexter]

I'm presently in possession of an LC Smith Monogram Grade 12-bore used by a famous lady live-bird and trap shooter named Anna M. Rieker (maiden name) in the hopes of featuring her story and gun in the DGJ. Information has been difficult to find with most coming from old news paper clippings; some of which have faded and others with grainy photos of Anna holding her Smith, but others show her holding what appears to be a straight gripped Parker SBT. Obviously I've wondering if anyone might have any information on this SBT, which I assume still exists somewhere? One of the primary issues in researching Anna thus far has been her name/s. She began her shooting career as an unmarried woman and was primarily known as Anna M. Rieker, although her last name was sometimes spelled "Riker". In about 1910 she married Lewis G. Vogel and began to shoot under her married name Mrs. L.G. Vogel (as was proper for the day), and sometimes Anna Vogel. Lewis died in the mid-20's and after being a widow for several years, Anna remarried and became known as Mrs. Wm. G. Cavers. She was also a member of the Westy Hogan shooting group where she was known as Nan Hogan; and finally did some shooting under the name Chief Shooting Squaw. Again as noted, I'm interested in any information but primarily want to know if there's any record of a Parker SBT being sold to one of the above named ladies.
Many thanks, Tom Archer
