Hi. I don't usually do model ships (mostly armor), and when it comes to ordering ship details I'm at a total loss. I am going to build the Trumpeter USN England/Buckley. I have White Ensign P/E which seems sufficient except for the AA armament. Nothing looks worse than flat 2-D guns especially in 1/350. I would like to replace the Oerlikons and Bofors with either turned brass or resin items. Is there a hobby store in either US or Canada who sells these types of replacement parts? I don't really want to order overseas.

Try free time hobbies. They have a large seclection of after market items.
Cheers,
Bruce
