ok here is a quick snip of some of what I view as 'surplus' and to be made available to folks here.
There are many many more parts but here is a start.
I've put prices on most parts where I have a feel for what they should go for (let me know if you think I'm miles off)

There are a couple where I've no idea so £? for those if you can suggest a value I'll list those separately as sale items
