3 Truck Shay G Scale

[superdog404]

Does anyone know how to remove the number plate that is on the front at the smoke box. Switches are behind it. I tried a heat gun. That warped the cover some. Didn't move the number plate. I then tried drilling it out. I got it out but was a very messing out come for the hatch cover. I have a number 5 badge now but I am afraid to try and remove the one from my good hatch.

Thank you
Harold
