N scale undecorated F3s and F7s

Do intermountains n scale F3s and F7s come in undecorated because i can’t find them anywhere if the do. If not is there a company that produces these models undecorated or do I have to strip paint on factory painted versions to repaint them in Soo colors?

thanks
john

Intermountain does not produce undecorated locos. Kato did produce undecorated F3A/B sets in their 2003 run. You might be able to find some of those laying around somewhere or on ebay. If not, Kato does sell undecorated shells for them, although the price is a bit salty ($25 a pop).

thanks
