Jon, I have just grabbed a picture of the real engine 226 in the Boro I was born and raised in BROOKLYN and was so very pleased to see that this is an exact replica of it --- right down to the air conditioner! It only needs a flag!
I think stickers from a store like Michael's will do! If you need the original to post here I'll add it to one of my creations, swipe it and use it! Nick
