Where to sell and indication of price - CB bundle

Hi I’ve been given a load of CB radio and related stuff, all quite old, but apparently tested and working, although I have no idea so can’t confirm. It is all in immaculate condition. 

The person who has given them to me has asked me to sell and give the money to a local dementia charity, but I have no idea of values or where to sell. Is anyone able to give me an idea of what the stuff is worth, and where is best to sell it?

I have:

7 aerials
Handheld microphones 
Eurosonic SWR 2T band power meter
Mustang CB 1000 cab radio
Zenith Speech processor (boxed)
All manuals plus books
Superstar CB 2000 CB Radio (boxed)
Audioline CB 27/81 CB Radio
Power Reducer
York CBS 869 CB Radio/microphone
Colt 295 CB 27/81 CB radio/microphone
Maxcom 7E Alert Mobile Transceiver (boxed with original packaging and instructions)
2 x 13.8v/3amp dc power regulators
Bell/siren 
Bremi BRL 31 amplifier (boxed with original instructions)
3 way antenna selector 
Midland 23-134 power meter (boxed)

There is probably a huge amount of mistakes and I have pics of all that I can attach, but just looking for a starting point….thanks

You will maximize your profits by listing each item individually on eBay, it appears to be pretty dated equipment in the main but you will find some guide prices by looking to see what these models have brought in the past.
The simplest option would be to offer it as a job lot on there, it may be an idea to see if anybody local to you could look it over to see if anything is of a higher value and separate it from the lot such as the Superstar 2000 Multimode stands out at a glance.
