Holland & Holland

I’m looking for info on H&H, anybody have a link to the companys history? How many calibers had the H&H name on them? and finally I want to collect these rounds either loaded or even brass anybody have a source woth reasonable prices for 1 of each of these cartridges? JH

Holland & Holland. The Royal Gunmaker by Donald Dallas is the definitive book on the subject but if you just Google the name you will find everything you want eventually.

The company is still very much alive and kicking.
