I'm not familiar with Cosina branded lenses, so I don't know what construction methods they use. One very safe possibility to try, is to see if the front name ring can be removed by unscrewing it CCW while holding onto the focus grip with the other hand, and if it does, then there might be a locking ring beneath that to give you further access. Use a rubber stopper or something similar (that won't touch the front element) as a friction handle. If that doesn't work, at least it won't be a method that would damage anything while trying it.
