Crispus Pugio Help

[Doc]

I am having the Alleriot pugio made for my centurio impression. I know that since the deposit date for this pugio is 69 AD, that I could probably use it from Claudius to 69 AD. However, since I would like to have two periods for my kit, I wonder if I could use it pre-Claudian; Tiberio-Claudian. I have the gladii from thess periods (Mainz and Pompeii), however, I am missing pugios.

I know that the Alleriot is a Type A pugio and I think (please correct me if I am wrong) that these types were used throughout the entire 1st C AD. Thus I figured that I could use it for an earlier or later 1st C impression.

What about the Velsen? Is this not a type B pugio? Didn't type B pugios come after the A or did they coexist. I know that the letters do not desginate time periods but styles. However, from what I recall the type B pugio came later than the A. If this is true, then the Velsen could be used throughout the entire 1st C AD-no?

I ask about the Velsen because if the Alleroit is too late for the Tiberius period, I would think that the Velsen could cover it?

What is the earliest Type A found and the latest Type A found? How about the type B earliest/latest?

Thanks in advance for the help
