ehall928_ your stamps are type II(Scott).The overprint types can be dtermined with the pic below.The main ones being I & II.
There are also the positions in the vertical block of 12.(2 x 6)
In your stamps (the first 2 are not clear).3) pos. 2,4) pos.4,5) pos.2, 6)pos.2.
These stamps should fit into one of the 12 positions.That being said; it can be also a reprint.
Stamp 3 looks nice to me..
