The choke has mechanical damage but looks like electrically it would be ok. Measure the resistance of the choke from the the flying lead to the other end where it is attached to the board. If it is not an open circuit just solder the free wire from the choke to the hole in the board that has the wire stub sticking out of it.
A-205-1 is an Electra Bearcat part number. Outside the Electra company this number has no meaning and can't be cross-referenced to an industry part number.
The choke is not particularly critical. It is part of a high frequency filter in the power lead of the SN76643N integrated circuit. The users manual for the Bearcat 3 has a schematic like the service manual does. But the users manual does not show L6 at all - it has a resistor R7, 47 Ohms, in place of L6. I would guess that the service manual has the latest information and would not recommend putting a 47 Ohm resistor in place of L6.
If L6 is open circuited, you can measure L3 which is the same part number. Measuring the inductance and resistance of L3 would allow you to match a choke in a distributors catalog.
