I am hoping that someone might be able to help me by taking a close up photo or two of the area where the separate Vision Line Big Boy attachment is meant to fit into the hole on top of the boiler? I have the original whistle attachment piece and a replacement backup piece, and neither one fits correctly into the hole. My Big Boy has a round black plastic piece seated very near the surface of the boiler where I believe that the lower portion of the separate whistle attachment (specifically a round funnel looking piece) is meant to slide into to complete the design. But no matter how hard I try, the two pieces don't seem to fit together, and I don't want to force it too hard to avoid breaking anything. So I am trying to get a better feel for what someone else's looks like where it is working correctly to see if I can figure out if I am doing something wrong, if I can remedy the issue myself (i.e. do I simply have to shave off some of the plastic around the funnel of the whistle attachment to make it fit into the plastic piece seated in the hole in the boiler), or if I have a defective item that I need to send back to Lionel to remedy.
Just before posting, I decided to try to take a few photos of the whistle attachment area of my Big Boy. Perhaps someone can look at my photos and compare it to their working one and advise me whether mine looks similar or different. Photos were taken on my phone so sorry for the less-than-pristine quality. Thanks in advance for the help!
