Stik,
Monogram's Viper is 1/32.
Ikar,
The stripes are fairly simple. You should be able to make a set of masks from Tamiya tape. I just checked Starship Modeler's store and they have a set of masks for sale that should work. I think Paragrafix made some as well. I should probably finish mine up, it's been on the shelf of doom for almost 30 years.
