winter projects, need info.

[911JB]

I am looking for info on 3 revolvers.

 The first [top left] is a US REVOLVER CO, top break , looks to be about a 38 cal.

 Second [ bottom left] is a IVER JOHNSON ARMS & CYCLE WORKS, top break , posibaly a 32 cal.

 And last is a THE AMERICAN     DOUBLE ACTION  , solid frame, looks to be a 38 cal also.

All three are, or I should say were chrome.     

Anyone have any info on any of these revolvers?       

 Thanks in advance for your help.
