Swan 14 A, DC Converter for the Cygnet and Cygnet-like model transceivers

This Swan 14 A, DC Converter for the Cygnet and Cygnet like model transceivers, is in excellent condition.

This is a plug-in dc converter (it is not a stand-alone power supply, but an inverter that attaches to the Cygnet
and Cygnet-like model transceivers) that provides for 12 to 14-V dc mobile operation of the Swan 270B, 300B,
350A/B/D transceivers. It is designed specifically for the Cygnet-type transceivers that have built-in power supplies and is not interchangeable with the 14C or 14X. 

 I have not tested this unit but it looks to be in excellent condition inside and out.
