Help identify Mosquito airman - check signature

[Adriano Baumgartner]

Good night to all.
As posted previously, I possibly took for Edwards´s Navigator this airman´s signature below on the link.
He gave this book to a former Mosquito pilot, whose widow sent it to me. As we can see he flew from Scampton, Lincolnshire in Nov. 1944 and was 27 years old at that time. He mentions a certain picture 57 that I took for that of W/C Edwards boarding his Mosquito Mk IV.
Please can someone identify this signature. I have checked again the book and checked for photograph number 57 and NOT page 57 as I was thinking before. The photo that appears as number 57 is that of Mosquito Mk IV serial number DK338.
Can someone link me to a possible candidate of this signature, someone with Chris as second name?
Thanks in advance
Adriano
PS: I tried to post the original file written by Hptm Krause on the flights with Dornier Do 335 but it was too big...Will post it later/tomorrow.
Yours
