Mauser markings?

I have a few parts that I don't know what the marking are. Hope someone might know what country they are from.

I think the Crown over H is an early (pre WW1) Serbian proofmark.

Thanks for the info. This trigger guard was on a K98 stock. Would a pre WW1 trigger guard be the same size?

They used Model 1899, 1899/07, 1899/08, 1910 and 1908 mausers before WW1. Some if not most rifle parts based on the Model 1889 design should fit on a K98k.
