Thank you for the PDF conversion.
I noticed in the RFB thread that you were requesting additional info on the models introduced by that mod. Maybe you can convince them to provide a link/DL to the source(s) used for creating the new models? Those would probably contain the ships lenghts you require to complete the list.
The only sources I can find at the moment are CD-ROMs that you need to buy and
this, but it doesn't list any merchants.
