I have been unable to find any info on just when the 9W3 & 9W4 were introduced. Both are listed in the 1908 catalog & are stated to have Singer Decoration.
I have copies of small (Not Complete) Singer catalogs from the US for 1908 & 1913 & for the UK from 1911 & 1912. The US 1908 catalog shows the 9W1 & 9W2 as both having W&W decoration & the 9W1 is pictured in W&W cabinets. The 9W2 is shown as having both the belt pulley & gear for the crank. & is pictured in a W&W portable case.
The 1911 UK catalogs only show the 9W as a treadle & while not stated as such it would I believe be the 9W7 as it is shown in singer cabinets & with Singer decoration. neither show a hand version.
The 1913 US catalog does not show a 9W at all, but does have the Singer 115 rotary listed.?
I highly suspect that when Singer took over the W&W factory there were many machines in process at various stages of completion. No doubt there are many that do not "Pigeon Hole" into nice little categories as we list them today. It would sure be interesting to get more detail on that machine you posted about.
