Help, I'm having an old man hates internet moment.

I purchased a large lot of vintage lego this week, well because it was close to my house lol.

I'm trying to id some pieces to see what sets may be in the lot (5KG).

Below are what I would call unique pieces - bear in mind I have not touched or looked at lego for 20+ years. I can remember when green lego was first released.

If someone could please provide some guidance on what the best resource to ID parts is and maybe some hints I am sure I will be away. (well back to the pile of lego for the rest of the week).



The mini figures that came with the lot vary from space to castle and some police or firemen.
