This is a Lotus 7L2, Gen2, made of brass. It is said to have undergone annealing treatment, similar to the Monette Prana. The 7-rim L2 cup is currently made to order. As Adam says, I believe all models are perfectly intonated, but despite that, I ended up buying several due to individual differences beyond generational changes. My main mouthpiece was a 3L2, but since I can also play a 7-series, I tried two 7L2 brass mouthpieces and one bronze, and decided to keep only one of the 7L2 brass mouthpieces and sell the others, hence this listing. For users who find the Gen3's incredibly smooth texture to be so slippery that they feel like they might drop it three times a day, or whose gold-plated rim slips when they try to play, causing them to accidentally break a front tooth, the Gen2 is especially recommended. Moreover, the blank is cooler compared to the Gen3. The craftsmanship in the recessed part is different, with the Gen3 feeling quite rushed. The L2 is very well-made, so I believe it can handle everything from section playing to combo playing with just this one mouthpiece. It's also a great point that it's easy to play and doesn't have the kind of strong character that destroys the instrument's nature like a Monette (lol). There are no dents or other issues that would affect playing, but since it has been played quite a bit, there are minor scratches. (The scratches might come out with a little polishing, but I don't want to polish it, so I've left it as is, with only a light cleaning using Buzz Silver Cleaner without excessive polishing.)
