7" MAK coatings

Does anyone really know?

I have a used 7" MAK OTA in good shape. Is there an easy way to tell if it has UHTC coatings? Is it somethng as obvious as an engraved UHTC on the name plate, or a color seen in reflection when looking into the OTA? It's ot the counterweight inside, so most likely came off a fork mount, but I don't know if it was an LX50 or LX200.

Thanks,
Steve

Steve, check the under side of the OTA near the back end. I think they put the stickers there sometimes.
