Looking for Wharfedale E90 Xover information

Hello,
I am French, so sorry for my poor English
I am in the process of building my own pair of Wharfedale E90 speakers I dream of for a long time but cannot be found in France.
I already have 2 pairs of E70 models I really love for a long time, mainly for classical music.
By using the speakers of both E70 1 can quite easily put them in a E90 case of my own, keeping the exact internal sizes and features of the original E90. I already made several DIY speakers.
My main problem is the crossover. I didn't find any information about it. I found 2 crossover in the UK for the E90 Pro, PA version of the E90, the printed circuit is the same as the E90 but some components are missing because this is a 3-way model (700 - 7000 Hz if I well recall) while the e90 is a 4-way (150 - 700 - 7000 Hz), each boomer having its own way.
So I am looking for either a photo along with the value of each inductors, caps and resistors, or a schematics with values.
Hoping that one of you guys will be able to find out this old information or open its venerable E90 to take a photo and copy the values.
Thanks in advance
