HPE (or adding a new) brand on create new device entry page?

HI All.
Firstly need to apologise....

https://openwrt.org/toh/hwdata/3com/3com_1920-48g_jg927a_hng7a-ha0015

Working on creating an HPE JG927A wiki page and ToH entry.
I made a mess of it and now have 3com instead of HPE.

Editing the brand after the fact got it to a point where It turns up correct everywhere except for the brand name in the hpe/start part.

I'm wondering how users managed to get the new techdata page right when there isn't the "hpe" option in the add new device form. (Or with there being no "switch" field in device type)

Per this:
https://openwrt.org/meta/template_dataentry_background I don't want to be breaking the rules?

Would be great to get feedback on how this was achieved?
I would then be happy to create a tutorial or update other wiki pages?

Also I noticed that @tmomas isn't active on the forum but there's a @standarduser which I can look up when it auto fills for @tmomas as it's called tmomas standarduser?

edit:
Found that the new wiki account forum post indicates that there aren't any wiki admins active on the forum and to try IRC. I have done that today....

edit2: I have created a page for JG928A. Also turns out that the form allows you to submit the "please select" option as a valid input?
