'P' is the key

[tavie]

Okay, I'll entertain the notion you weren't intentionally lying. Here's what I have issue with.

This is the second spat you've been involved in on this thread after asking for respect.  You're not going to get it when you make such accusations.  Please tone it down.

I'm going to make one last image, but its clear that you're doing this deliberately or using an LLM with memory loss. You cannot possibly not understand what i'm saying.  The vellum is 29x41cm, and on that vellum is a map of size 22cmx19cm. 

I would suggest there is a third option:  they genuinely misinterpreted that "vellum" only pertains to the portion of the map because the word appears immediately before the map's measurements in the below description, rather than at the end where the sheet's measurements are.  

Map with Ship: 1 map : ms., vellum ; 22 x 19 cm., on sheet 29 x 41 cm. (You are not allowed to view links. Register or Login to view.) 

At some point in this thread, I have missed what the merits are of having a dispute on what precisely 'vellum' refers to, and I'm not putting myself through reading it again.  Surely the key point is that there is a sheet - let's not mention the v word for argument's sake - that measures 29 x 41 cm, and on that sheet there is a drawing of a map that measures 22 x 19 cm?   We can all agree on that, right?
