Bayonet

Hello Everyone
Can anyone recommend a good book on collecting bayonets. One that covers all countries would be good, but with the emphasis on British and German ones would be great.
Thanks
John
I've added some photos of a bayonet I've been given, anybody any idea what it is please?

 

Looks like a Czech 8mm Mauser /Gewehr 98 bayonet? The 'csv' is Czech manufacture mark I think. I know nothing about bayonets, but this site is great:

Thanks for that BrianM59, and thanks for the excellent link to the website.
Cheers
John

 

What you have is a VZ24 Bayonet. They put the cutting edge on the top. Usually very well made.
