Spain 1860 4 cuartos

I have recently received a lot of these stamps. Here is the first post, related to the Cartwheel marking ('Rueda de Carreta' in Spanish) from Barcelona, RC 2.

Here I show a comparison of the numeral. I am guessing that there are at least six unique types, and perhaps more. It is easy to categorize a single type as two because the same type can look quite deferently depending on wear.

I found one type repeated and with a small bump at 7 o'clock.

I also find a few other with breaks. These look like breaks and not gaps caused by the angle at which the mark was punched on the stamp.

I also have Picasa web albums of the stamps and the numerals here:

In reference to the color varieties, I find there major categories: orange, yellow orange, and orange yellow.

I have added to my site dated copies of this stamp for the three years of usage I have. Does anyone have it used on 1863 or thereafter?

I have also looked for plate varieties and have group them based on three parts of the design:

Varieties of the denomination (4 CUARTOS)
