Help With Sg Number- GB Two Shillings

I believe this to be Illustration no. 32, maybe SG118 - but I do not see a listing for plate 1 with Specimen overprint. Looking for correct SG number help please.

Does your copy of SG show any GB specimens? There used to be a note in the introduction to the Commonwealth to the effect that GB specimens are only shown in the Specialised.

I'll be with my Commonwealth in a few hours, and I could put my hands on my Specialised in a few days.

J118u, specimen types 2, 5, 8, 9, 10, and 11 from £ 100 (2001 specialised).

J118 is SG Concise 118 - 120b, depending on the exact colour.

@NSK - thank you.

Im a little confused. I only have Great Britain Concise 2021 catalogue. For SG 118 - 120, I didnt see Plate 1 listed perforated. So what then?

EDIT: So, I DO have Commonwealth & British Empire Stamps, 2021 Edition.... I did not think to look there because I thought that was only for issues outside UK. I need either a catalog lesson or Geography OR BOTH!!

Sooooooo..... USER ERROR - apologies - I was reading the Specimen types in brackets as plate numbers. SG118s for me. Tks again.

SG118-120b were perforated, as were all surface-printed stamps.
