Would anybody know if it is OK to key a Century 21 with a HAMCO "Carson" keyer (I think it is pretty much the same as a "Scotia"?)?  If they're not compatible, can you recommend a reed relay that I should order, or another method of keying the Century 21?  Thanks.

The Ten-Tec Century 21 transceiver
http://www.rigpix.com/tentec/century21.htm

does NOT have an internal electronic keyer for usage with a "twin" or iambic style paddle (Hamco, Scotia, Vibroplex Brass Racer, Bencher BY-1).

The Century 21 works with a straight key or semi-automatic (pendulum action) bug (Vibroplex Original).

Several small extrnal electronic keyers ont he market (including a couple from Ten-Tec that matched the Century 21).

The Century 21 (C-21) was Ten*Tec's answer to the call for a low priced, entry level, novice rig in the mid 1970's.  
Very popular, and the C-21 helped many Novices upgrade to General class quickly.  This is partly in thanks to the attention paid to its superb CW operation including 3 filter bandwidths.   Direct conversion receiver, but without the broadcast band blow-by of the Power Mite.  
The C21 was also available as a "digital" version with large LEDs replacing the dial.  35 watts RF output, 80-10 meters.  120VAC powered.  

BE PREPARED to rebuild the PTO of this transceiver (known, well documented problem).

No Big Deal @ $25 and a couple hours of your time (or a technician's - IF you can not handle small parts).  

Here is Monty, N5ESE excellent website on the C-21 PTO REBUILD
