Finding an original loose fork for an Ideor will be a challenge. The original crown while not unique I have only seen on similar age Galmozzi bikes.
There is a "for Sale" sub forum where placing a sales advertisement would be appropriate. For that you would need to buy a paid membership which is modest in cost. But you would need to come up with a price.
Ideors are often nice bikes, they made a pretty wide range of them though, so no telling of your bikes' value and interest. the top line bikes are the sought after ones. Too bad about the paint, many were chromovelo in finish, where there was a tint over a chromed frame.
