Hey, any Rodgers Trio owners willing to help a guy out with some dimensions?

I'm building a virtual theatre organ console using a Rodgers Trio stoprail, and need to figure out some measurements and angles.

See attached diagram. I am looking for the dimensions a through g, in inches if possible. Dimension "a" is of the sloping side with the top lifted up (not including the top plate with the horseshoe cutout). Dimensions d, e, and f are of the lid (the sloping part with horseshoe cutout and the flat part).

Thanks!20170809_192827.jpg
