Xmas Lights (Calver S32)

Two sets of Xmas lights, to go together.
As per usual they worked when I put them away last year but now won't come on.
Both are mains plug in type.
If anyone has the patience to sit and twiddle each of the bulbs you may get them working.
I haven't got the time or inclination, so have given up on them this year and will get some new.
Can be left undercover for collection to make things easier.
Please give tel no. in your reply.
