Very hard to give a valuation without Photos but a little further information would help.
On the Premiers, there is a letter engraved on the frame in between the trigger and grip . What is that letter on each gun please?
I bought a similar sounding pistol to your first one a few weeks ago off here from Vic Thompson for £150
A boxed Hurricane my guess is £140-£150
An unboxed painted 'E' ( Label ?) in good condition about £120-£130
As a cash job lot, £400 sounds about right to me. Don't know what anyone else thinks
