The only photo I've been able to find of the Vimy's cockpit is here:

That only shows a compass, altimeter and a slip indicator. Although they penetrated clouds, they were not exactly equipped to do so. In contrast, Lindbergh's Spirit was better equipped for this. Then again, the instruments in the Vimy were all that was available at the time.
