You need to look for the dnspython head object in the dnspython repository. E.g.:

% GIT_DIR=.git/modules/third_party/dnspython git show 43c14fd73b3b94211ff8bfad8f894b48cce4e577

or alternatively:

% echo ../modules/third_party/dnspython/objects >> .git/objects/info/alternates
% git show 43c14fd73b3b94211ff8bfad8f894b48cce4e577

does that meet your requirements?

Cheers,
