Help with 505 Gibbs Head Stamp, Please?

[Varminthunter23]

Hello All… I came across some brass I’ve collected for a 505 Gibbs rifle. The Head-stamp is “H H”. I wondered about Holland and Holland but can’t find any made. Looks like pic below. Could someone help identify who is the maker on this? Thanks so much!

Brass is considered top notch! Was able to buy 505 Gibbs direct from him in the day. Herr Horneber has since retired.

Thanks so much for the info!
