Can you help to identify these frames, bikes or parts?

Can anyone identify these brake levers? I'd like to replace the hoods but hear that they are specific to the levers and hard to find so am reluctant to rip them off without being confident of finding replacements.

I can't find any model type on them or even any pics of similar models on the google... Similarly the shimano hubs don't have a model type ont hem so if anyone knows whether this was normal for shimano products at a particular time period that would be interesting to know too... Thanks for any help.

I had these on a bike that was full Shimano 600 except the brakes which were 105. So I always thought they were golden arrow. Here's mine:

and here's the golden arrow:

Now I'm not so sure!

*Edit if you do get rid of the hoods, I'll have 'em!
