The spring sits proud of the plunger.
I must admit that i haven’t tried these in a frame. It is possible that they are not particularly suited to the finescale tolerances.
I think from your comments and my observations I will temporarily withdraw them to see if they are suitable or not. I am in the middle of building a chassis myself so i will see how well they fit
I know they have been available for quite a few years now so I wonder how OO modellers got on with them
Thank you for letting me know your experience of these. With the number of items in the stores it is often difficult to know just how suitable they all are
