They are German WWII Navy Artillery 7 x 50 binoculars manufactured by E. Leitz, Wetzlar. Yes, they are good. Are the optics clear? Focus adjustments working and smoooth?
I see bakelite and Third Reich era manufacturing codes, overall condition , i would jump..when you see enough of them, file it away for the next time and make the jump with a less queasy feeling!!..with E-bay, there is always a next time!!
If they were artillery they would probably be art. marked and would have ( most likely) a graticule in them. As they stand a good set that would clean up well , no eye cups though - they are missing. The coverings are missing off the objective tubes - few of this type have good coverings - usually dry , cracked and ready to fall off.
