MARK XV - Ref. 3253 - IWA-no. of the steel bracelet (rice-beat-style)?

Hello,
I am desperately looking for the Part-No. (IWAxxxxx) of the early version of the Mark XV's 19mm steel bracelet - so called rice-beat-style. It came with the Mark XV within the first 2-3 years and looks similar to the one that was mounted on Mark XII / Kleiner Fliegerchronograph, but has 5 "fingers" to the case link instead of the 2 ones of Mark XII.

Unfortunately the renowned Workbook-Search doesn't show a result with newer browsers.
Any advice is highly appreciated.

Ticking regards from the Baltic-Sea

The "Old" from the year 2000 Workbook

And the "New" from the year 2004 Workbook

The bracelet for the Ref 3241 Mark XII is given as A01936 in the year 2000 Workbook

Wow! That was much faster than I have hoped. Exactly the info I was looking for.
Many thanks from the Baltic Sea.
