[6pack] TR6 Engine Number

[Bob Danielson]

Can anyone clear up an engine number question for us over in 6-Pack. One of 
the guys with a '73 has an engine number stamped CD120UE yet according to 
Moss & TRF there are no 250's or 6's with an engine number beginning with 
CD. You can see a picture of the stamping at this URL

Were warranty replacement engines stamped this way? Any help would be 
appreciated.

Thanks
