First, an old thread here:

This, you may have seen, but it does have a decent three-view:
Vickers F.B.19 - fighter
This is a period three-view with dimensions:
Vickers Scout
I have a copy of an old Cross and Cockade that has a couple of photographs of these machines in service in the Middle East, and the old Harleyford 'Fighters of 1914-1918' book, which has a write-up on the type, including a good three view. If you sent me a private note here with your mailing address, I would be happy to send you photocopies. I do not think any of my material has information about interior arrangements, unfortunately.
