If the scratch is deep enough... paint it!
If the scratch is deep enough... paint it!
A deep scratch in a front element can be made to disappear (if it shows at all in images)
Remember, abuse on the front element often does not show in images... on the rear elements.. you have a problem.
A single bristle brush laying black ink/paint IN the scratch may prevent it's capacity to throw a flare into the lens, and may not show up at all in the image.
Have done this before and found it useful.
India ink is good.
LOVE the Yashica Electro 35CCN. Excellent little rangefinder with a unique focal length.
As far as finding other CCN's or parts, have you checked with the YashicaGuy on the internet??

If I were looking for someone to repair the lens, perhaps find an element, i would check with
www.focalpointlens.com
John at Focalpoint was informative and they did a wonderful repair on three surfaces of my Mamiya 75mm Press lens with separation.
LAST NOTE:
One CCN parts camera on eBay, and 8 CC models. right now. All prices look good, with the parts camera $45 or best offer.
