Help determining a fair price to ask for an un-numbered byf Trigger guard complete with follower

I’m looking for some assistance in determining a fair price to ask for this trigger group. It’s an original late war byf phosphate, along with the follower and spring. Any advise would be helpful. I just don’t want to appear as if I’m trying to be unfair to fellow collectors.

Thank you….any ideas on price range?

Nice late rig...not cheap.
150-175 for group
