>> bodies.  Older eyes have the "condenser" logo and newer eyes have  
>> the Leitz
>> Wetzlar logo.  According to convention ( which I haven't confirmed)  
>> the
>> newer eyes shouldn't be compatable on the older DR bodies due to  
>> the ball
>> bearing size difference.  My DR has the new logo and the older body  
>> so I
>> was curious if I could find any other examples of this anomaly.  I  
>> searched
>> ebay and the internet for examples where the age of the lens and  
>> logo of
>> eyes were identifiable.  Here is what I found:
>>
>> 1956- 125,594 lenses made
>> 1402xxx Old Body Old Logo
>> 1403731 Old Body Old Logo
>> 1440268 Old Body New Logo
>>
>> 1957- 89,389 lenses made
>> 1487412 Old Body New Logo
>> 1513415 Old Body New Logo
>> 15301xx Old Body New Logo
>> 1534320 Old Body New Logo
>> 1545576 Old Body New Logo
>>
>> 1958 -97,281 lenses made
>> 1587819 Old Body Old Logo -From Cameraquest website
>> 1592570 Old Body New Logo - My Lens
>> 1623068 New Body New Logo
>>
>>
>> The only exception is from Cameraquest where Steve probably used an  
>> old
>> example of the eyes for the old body. Who but Steve would have lots  
>> of
>> these hanging around?
>>
>> All this suggests that eyes with the newer logo were manufactured  
>> with the
>> larger ball bearing receptor for the older DR bodies.
>>
>> The ball bearing size on my older DR body is 3 mm diameter and 1.8mm
>> height. The receptor dimensions on my eyes with newer logo are 3.5 mm
>> diameter  and 1 mm deep.
>>
>> It would be interesting if we could fill in these blanks regarding  
>> ball
>> bearing measurements on the older and newer DR bodies and eyes:
>>
>> 1)  Older DR body: 3mm dia x 1.8mm height
>> 2)  Eyes with older Logo: ???
>> 3)  Eyes with new Logo on older body: 3.5mm dia x 1mm depth
>> 4)  Newer DR body: ???
>> 5)  Eyes with new Logo on New DR body:  ???
>>
>> The supposition is that the dimensions of1,  2 and 3 should be  
>> similar
>> while 4 and 5 should be different and smaller.
