Everybody makes mistakes, even historical groups. The NHRHTA had a custom run of Intermountain box cars done in two paint schemes, delivery and the final NH paint scheme. Unfortunately an extra serif somehow ended up being added the the N in the logo. I simply used a #17 chisel blade to scrape off the offending serif. I did ding up the box brown paint a bit, but I will be able to cover it up when I weather the car. the fix took less then 5 minutes.
