Harry, at first glance I spot quite some period correct versions of the tools!
Rare early red screwdriver, correct large pliers, wheel pin. Allen key#10 is often missing, your set has it. Feelergauge and valve tool seems to be there.
For those interested, I do have an original small pliers to make it complete.
If you can add some detailed pics of the text on the spanners "No350" and "No450", that'll make it even more interesting.
