The Parks Gold Series are classic 'pseudo-Masuyama' eyepieces like Celestron Ultimas, Orion Ultrascopics, etc. The design uses 5 elements and is still being used by Takahashi in their LE series. The fifth element allows for greater correction than a Plossl.
It's in excellent condition with some minor scuffs on the outside. Glass is perfect.
Will supply with generic eye caps if I still have them, otherwise in a plastic case.
