The Voynich Manuscript:Decoded ( theory )

[Ruby Novacna]

Are my eyes deceiving me or did he genuinely include an image clearly not from the VMS and claim it to be?

You are not wrong!!  He even further annotates it as "Figure 39 VM Object Showing Name “Alfonsina.”  

At the same time as voynechese I'm learning English and I had understood the sentence
"These indications may explain why the VM features the
illustration of a tube, conduit, hollow column or canon barrel labeled
“Alphonsina” (Figure 39)" 
that VM presents in its images an object presented elsewhere under the name of Alphonsina. 
I regretted when reading that the author did not quote a reference. 
However, I don't think that the author claims that the image of Alphonsina comes from VM.
