Here is a website that allows you to chose the specifics for the lamp you are seeking:

Light Bulbs Etc, Inc. - Miniature Lamps (http://www.lightbulbsdirect.com/lbe_mini_inquiry.html)

Note that you first need to chose the bulb shape and the type of base, asking just fro a threaded base is inadequate.

This page lists the available types of lamps, the combination of specs you need does not appear to be available.
