Buckle ID help

[BladeRunner2019]

I don't know anything about buckles so forgive my ignorance on the subject.

I found these a while back at several locations but never got around to posting/asking for help with them.

Any information (approximate age or ID) would be much appreciated.





Shoe buckle?




I assume this is a modern buckle but thought I might as well post it since I was asking about the others. The back reads: Solid Brass Made in USA.




I realize this isn't a buckle, but saw it in my box of finds and thought I would post to see if I could get any info on it. I assume its not a Jesus fish.


Thanks for any information you can provide.

Bottom item looks like the button catch on suspenders.

Next to bottom, military issue web buckle.

Above that, a web sling adjuster.

The bottom fish pic looks like a bottle opener?vanzutphen

Picture five ans six are a military web belt buckle, I was in the navy in the 50's and wore a belt with a buckle like that on my work uniform dungarees.
The last item might be to small for a bottle opener, but back in the 40's, perhaps before and after, I'm not an expert, women had garters to hold up
their nylon stockings, and that looks like part of one of those deals.
