2 different curved tang stamps used by Colonial

[B.Mauser]

Have you guys noticed there are 2 different curved tang stamps used by Colonial?

I have about 8 Colonials with curved tang stamps in my collection. 1 is different than the others.

I have searched this on google and looked through all the curved tang stamp posts here on AAPK.

I haven't seen another like it.

Anyone know about this or have one of the different tang stamps?

The one I see more of has the curved Colonial with Providence under it and R.I. under that. Cant see the R.I. on some knives.

The other one I have has a curved Colonial at the top with Knife Co under that and Made in USA under that.

The o in Co didn't stamp well on mine and looks like is says Knife CC.

Here are the pictures.

First one.

Second one.

The knife its on.

Update.

I have been looking for another Colonial with a tang stamp like this one for a while. I finally found one.

Like the one above, this one is stamped Colonial Knife Co instead of Providence.

The knife its on.

The second tang stamp is stamped too far to the right and the end of the L in Colonial is cut off.

I think when Colonial was changing from the CKCO tang stamp to the curved stamp they used this one for a while. Due to both tang stamps having a defect I think this was a temporary one they stamped by hand while they set up a machine to do the more often seen curved tang stamp that was used until 1938.
