I seem to have four tubas - mainly good quality ones at that - which I'd like to sell.

For the record they are:
1937 York 'Factory C' (advertised elsewhere on this site).
Melton Fafner (with dependent 5th valve).
1912 Holton Rusk-cut C 6/4 (4+1).
Miraphone 183 bell-front (no dents but seen a lot of use) 4v.

I'm thinking about the EBay route and wondered if folks could offer up any advice about how to get the best from the EBay system? I don't have ANY feedback btw...

The horns are here in the UK and the market for front action tubas is pretty minimal. I don't really mind where they end up as long as the buyer is good. Can I advertise Worldwide or in UK, US and Germany with one Ad??

#I'd endeavour to be honest in describing an instrument.
#Obviously pictures should be plentiful, clear, and useful.

What about things like 'reserves' and/or starting prices and/or Buy Now's etc etc???

For something like a tuba, what's best practice for receiving money and how should I check a buyer is legit?

Is there a much better route for selling - I'm not in a huge hurry but need to free-up space and aquire some £$£$£$.

Thanks for any advice...
