I'm sorry..where are said casings..?
They may not be casings. There's a hint of something under the left wing, next to the little pitot (perhaps) probe thingie under the left wing. Since there are no gondos on this one, I can only conclude it must be something else. One appears under the right wing as well. They both look cylindrical. Given the probe thingie, I'm thinking K-4, therefore dismissed attachments and assumed casings, especially due to the blurry, vibrating "look".
