Are these a standard size or did they differ during production ?

The TE has had two,possibly three different types of whistle: the 'turned brass type' the 'sprung reset type' and possibly the button push down type - similar to the sprung reset version, these were not common.

Thanks to both of you for the replies and information. The whistle that is on now is locked solid and the body seems to be slightly bent through what I can only assume is light damage. I can't be sure but I think the centre section that pushes down under the pressure of the arm is thicker in diameter than the sprung centre section of the whistle on my other TE which seems smaller in diameter.
Once I get it off I will photograph it and post the pic.

Vinegar can help the release a seized whistle, even coca cola! There comes a point if its so bad that 'heavy' tools are needed to un-seize it, maybe even fitting a new collar in the boiler, but then the strip down gets serious. What you really need to ask yourself do you need to remove the whistle?

I fully appreciate your expertise and experience, your advice will be first and foremost whilst I give this matter some thought.
Perhaps what seems to be a steady camber in the whistle body has something to do with it being siezed, I dunno.
I'm not getting to serious about removing it. My reckoning is that it will eventually loosen with gentle persuasion, penetrant and the right size spanner. I have all the time in the world.

Sensible approach, Ive seen the bull in a china shop approach before and usually something breaks! Either the part of the owners patience.

Once the oil has had a chance to soak in, you could apply a gentle heat around the collar with a gas torch. This usually helps release any seized threads, a gentle turn with a spanner whilst it's still hot & it should be free.
