Help with Cattleya ID

[baulou]

This NOID Cattleya has flowered for me and I was interested to see if anyone could help me identify it or the likely parents. The person I purchased it from has had it in their collection for 25 years. My initial thoughts were mossiae (shape and spring flowering) but the lip looks like it might have purpurata heritage. There are also two ‘eyes’, which I understand might come from warscewiczii. It’s similar to Canhamiana or Enid, but also slightly different from both. Grower is based in Japan. Thank you, in advance, for sharing any ideas.
