[Boatanchors] Xtal needed maybe?

Last year i bought an AMECO  VHF COnverter model CN.  I didn't have any paper work on it at the time. but finally found it someplace due to a list members referral.  Got to looking at it today and realized that the Xtal frequency is not right for 6 meters.  It has a 12 mc rock whereas the tables in the manual (so to speak) show 43 Mc for a down conversion to the 7-11 Mc range for 50-54 mc coverage.  To cover 50-51 mc it recommends a 49.4 Mc rock.  

So does anyone out there have such an animal?  49.4 Mc or 43 Mc. preferably.

Output to the Hf receiver is variable so even a 40, 36,24, 22 or 19.5 mc xtal would work.

Now this converter is marked as a "CN" and not a CN-50.  Maybe i'm looking at two different things here.  If you know if there is a difference, even though this one has written "6 mtr" on the side, drop me a line.  I'll have to investigate this a little more it seems cause with a 12 Mc rock in it, the output would be 38-42 Mc.  Could it be that this is a 10 meter converter which would give me a 16-20 Mc output with the 12 Mc rock?  Also this unit has a BNC connector next to the 6J6 whereas the schematic for the CN-50 does not have that.  The Auto type connectors have been replaced by BNC type.
