Ertl collection

I will star, I have a tna diesel 10 and I got it when i was little, Even back when I was little I always had a thing for being very careful with collectibles, I know it can snap off but only if you twist and turn it in the wrong way, If you use it properly it will be fine. What I mean with play around isn't necessarily with pinchy, But D10 Himself on my ERTL Layout. I don't overuse those functions on my collectibles. I am aware of being careful.
