Hi
Check out Great Models Webstore
http://www.greatmodels.com/
They have a lot of pilots in 1/48th scale specifically by the manufacturer CMK. You can also check out Andrea Miniatures

They have some great pilots in this scale cast in white metal. They are a little pricier but well worth it as the detail is phenomenal.
I hope this helps!
Cheers
