Sorry! In case I conveyed the notion, I tend to make a secret out of the Store Ref. Nos. I am interested in: This is definitely not my intention. I just tried to prevent you from putting some effort in sending scans I already have. See the individual Nos. below.
Front up I should explain that this topic is part of a bigger project dealing amongst other aspects with the question how (volume and procedures) Switzerland sold war material to both the Axis and the Allies. Most of this stuff were optics, watches and special tools like lathes. As the old purchase contracts and shipping documents ended up in the bin, the approach is to establish on the one hand when where those things produced and when were there introduced into services and somewhere in between they must have arrived in the UK. So W10, titled "Compasses, WATCHES, SURVEY and Drawing Instruments" covers a lot of typical Swiss war exports.
As the publication of the revised version of W10 from 1956 in the LoC of August 1956 starts with the preface "The above-mentioned section of the V.A.O.S. has been revised from the 1937 (Reprinted 1948) edition and is hereby promulgated as the 1956 edition" draw my attention to the obviously existing 1937 edition, which should be amended by hand with all intros for at least the period 1937 to 1948.
Against this background I found:
Range Meter W10/VC 7542
Stereoscop W10/2048
Watches, Wrist, Waterproof (w.w.w.) W10/VB10025 to 10037
Watches, General Service Trade Pattern (G.S.T.P.) W10/VB10042 to 10052 [earlier designation VC 7392 for the whole category GSTP, while in 1956 edition each maker got his own Store Ref. No.]
Watches, Wristlet, A.T.P. W10/10053 to 10072 [earlier designation VC 7471]
Watches G.S. Mk. II (Mainly Swiss makes) VC 7216
The VB and VC respectively as leading letters might indicate these articles were listed in former times in section V2 Surveying and Drawing Instruments and Watches or V3 Flash Spotting, Sound Ranging and R.A. Survey Stores. The same applies to many Stopwatches, all originally designated to be VC.
While nearly all watches GSTP and ATP were made by suppliers by now longer existing the watches w.w.w. are very interesting with respect to several aspects: A substantial portion were made by major Swiss watch companies still existing today, thus allowing to establish the production date and the date they were prepared for dispatch. Although shipped from May 1945 onwards (Production in late 1944 and early 1945) they have got assigned lower W10 Store Ref Nos. than the GSTP and ATP, which were shipped and issued during WW2 (GSTP and ATP could be exported easily as they were not subject to the German "Geleitschein-System" due to their low quality). The w.w.w. were of higher quality and used the same works/works of the same class as the RAF navigational wristwatches 6B/159. For the export of 6B/159 and w.w.w. from Switzerland into other countries than Germany and Italy a German permission ("Geleitschein") was asked, but not issued (as the Germans knew from shot down Lancasters etc. very well, which watches the navigators used). So they were exported by some suppliers under deception, while other suppliers stood back at least until May 1945. May be the reason was, the Swiss were afraid to provoke the Germans, may be at the end of 1944 the need of accurate watches in the RAF declined, while the Army was back on the continent and in need for precision timepieces. To judge on each of these thesis is easier knowing the date, the Store Ref. Nos were assigned.
Best regards and thanks for your efforts!
