I have found references to the laws on multiple sites like Hurstwic but have not been able to find the laws themselves. Any help would be greatly appreciated.
Mods this did not appear to violate the rules but if it does please tell me.
I'm not sure how popular 'shield laws' as commonly known name, but I by change translated The weapon assembly section of Gulathing Law Book (Chap. 309), mentioning the shield, and posted here in this subreddit.
