Serial #'s lookup please

[mgmradio]

Hi Two Flints,
  I noticed you have access to lookup serial #'s. If it's not to much imposition I have a few I'd like to know more about.

  1865 Spencer
  Gwen & Campbell ( Union Rifle) carbine
  Starr carbine 9284
  Burnside carbine 5th model
  Smith Carbine

 I currently shoot the Burnside and Smith and am having bullet moulds made for the Starr and Gwen&Campbell so will be shooting them in the near future.
