Where Has South China Gone?

I am working on some Chinese stamps at the moment and I am having problems finding some in the 2006 Stanley Gibbons catalogue.
They are the "Liberation of Canton" series of 1949, featuring the Ho Nam Bridge. These are listed in the 1970 catalogue as SG# SC1 etc, under the South China section. There is no South China section in the 2006 catalogue and I can't find them in the China section at all.
Anyone know where they moved them to?

Try Scott 7L1-7L5

TonyG is right,Scott 7L1-7L5,Scott 2008 page 388.
Catalog value mint USD 1.70,used USD 1.25

I don't have or use Scott catalog,
but if I can't fing SG numbers that
may have to do.

Is that $1.70 and $1.25 each or the set?

Thanks Guys.

That would be per set.

Thanks.
