.30 TCU and 6.5 mm TCU

Does anyone know if there is a .30 TCU that was actually made by Wes Ugalde? I’ve seen some references to a .30 TCU, but it may be just a necked up .30/223 with a 40 degree shoulder. I have not seen one referenced as actually being made by Ugalde, most references stop at the 7 mm TCU.

Second, does anyone know the date the 6.5 mm TCU was developed? I have:
6 mm TCU: 1965
.25 TCU: 1987
6.5 mm TCU: ???
7 mm TCU: 1980

Thanks!
