I acquired my Trango on eBay from Legit Kit in 2022.
The Trango is forged from aluminum alloy and then soft anodized*. Mine is 172 mm. tall, 171 mm. wide, and 15 mm. thick. The rope hole is 67 mm. high and 76 mm. wide. The top center thickness is 12 mm. The shaft length and width are 47 mm. and 41 mm., respectively. The auxiliary hole is 30.5 mm. high and 15.2 mm. wide. The eye measures 34 mm. by 40 mm. The ears are 34.4 mm. long. My Trango weighs 243 g.
One side of the Trango is printed with a strength test icon (not a rigging illustration!) with "△" above and "▽" below, all above "40 kN," "TRANGO," "Italy," and "0103."
The Climbing Technology is a typical example of a forged aluminum rescue eight.
The eye and ears are larger than they need to be. The belay slot is a reasonable size for a Sticht slot, and insetting part of the slot into the useless portion of the upper rope hole reduces the length of the eight. Still, like all rescue eights, this one is too large and heavy for a normal climbing or caving eight - there are much better devices, including some eared eights, that are smaller.
Trango is a Korean company, but this eight was made in Italy. Climbing Technology undoubtedly made this eight, as the size, shape, and even the markings are nearly identical to the Climbing Technology aluminum rescue eight.
