That symbol is named 'per' and looks like

To me, the symbol looks like something that's not unifiable with anything existing in the standard. The loopy form is quite distinct and not similar to any other character in the standard with a letterform based on p.
Can anyone shed further light on this character? I assume this is a lower case form, does anyone care to confirm that?
I recently found anther symbol based on the letter p, this time, definitely a lower case letter. It's used with subscripted digits to denote papyri in at least one numbering scheme.
The following is the symbol as I find it in the source

Someone suggested unification with 1D513 MATHEMATICAL FRAKTUR CAPITAL P, but that makes no sense as it clearly appears to be a *lower case* letter, since it descends below the baseline. For comparision, our Fraktur forms are:
and

There is some resemblance in the way the bowl of the p is treated in 1D52D, but the decoration and overall impression are not like any Fraktur font I have access to.
Can anyone shed more light on this second symbol? Are there other sources that use just that form? Are there sources that seem to number papyri with the same notation (p plus digits) but use typographically different styles?
Can anyone place the font style for the specimen above?
