Ditto on the Pearsons being good bows. prices gave not risen like the older Bears, etc., so they can be had fairly reasonably. The markings on the first bow indicate a 62" bow measured around the curves on the back side, and a 58" string would be appropriate, Dacron only. The second bow would appear to be a 52" bow, measured the same way. The weight (xx40#@28") would indicate a 38# bow, measured at 28" draw.
If you are interested in values, check the auction site for completed listings for those bows. That will give you some idea.
My advice would be to just enjoy them for what they are, fun shooting older bows from days gone by.
