Good luck.  I like to a have some more of these as well.

I have considered doing a run of 60012 boards.  This would be
straightforward except for one thing: I have been unable to find any spec
for the transformers.  That part would have be to characterized.

Note that you can convert 5MHz boards to 10MHz by changing a couple of
discrete component values.
