Any info on Piega P8s? not LTD

Hi Guys,

I have some Piega P8s that I know nothing about. They were given to me MANY years ago by my ex who got them from a doctor who was trying to impress.

I took some pictures I've posted to Facebook:

Any info is helpful as I've posted them on Craigslist and really have no clue what a fair price is.

Thank you!
