Original New Old Stock Piper L4 Nose Bowls top and bottom

[NC1776]

I need some help being fair on a price. Would anyone hazard to guess what a set of Piper New Old Stock nose bowls for a Piper L4 including the factory induction box be worth. They are almost perfect original olive drab. There were in paper and I took them out. Most likely one of the only sets of new original piper nose bowls left out there. Condition is almost perfect, maybe a small dimple or two from 50 years of moving around. I want to price them fairly but hate to give them away also. Need help asap.
