Download Solaris Skunk Werks, and you can get them yourself.

It needs to be a jpg or a png file to work with TTS.

How hard would it be to convert these to the Record sheets that have all of the extra charts for movement, cluster tables, etc? I really love these, but would love the sheets with additional info.

NOTE: I've labelled all of the record sheets with their tonnage, model, and designation.
Instead of lauching the workshop mod from the TTS main menu, load whichever table you will be using and then open the workshop menu.

Find the Starter Box Record Sheets mod, and click the drop-down button, and you will be able to select which record sheets you wish to use.

Will be swapping record sheets from png to jpg over the next couple days to improve performance in-game.
