Nothing on the dating for you, but both shoes would serve you well for wear.
Biggest issue is are the soles and heals okay. The brown long wings look like they are good although neglected as previously mentioned. From your pics I don't see any black mold inside so if they fit and there is no obvious damage (splits in the leather etc.) then they can be revived and be an excellent pair of shoes for you with nice patina. That is if they fit correctly.
Here is what I would do to them. By no means a guru, but here goes.
First off, get some shoe trees to keep in them. Even in their current state I'd use them. Keep them in and be sure to place them in immediately upon removing the shoe from your foot after wearing.
Remove the laces, replace as needed.
Wipe the shoe down with a damp (not dripping wet) cloth. Get an old tooth brush and clean in the welt area. Get the dirt and grime out of there. Do not soak the shoe.
Once clean, brush them well with a good horse hair brush (including the tongues of the shoes).
From there I'd use a good cleaner/conditioner or leather lotion type product. Apply evenly and not excessively. If the leather is hard and dry then once the first application has soaked in and is dry you might want to apply another coat. (I use various products depending on the shoes I'm working with. Sometimes Allen Edmonds products and sometimes Saphir).
Once the shoes are dry I brush them again and wipe them down with a soft cloth. Just to make sure all is buffed even and there are no globs in the perforation pattern.
Then comes down to what you like for polish. If you like the coloring of the shoe as is then maybe a neutral polish. Otherwise you can use a brown polish that approximates the coloring of the shoe. Apply in light coats as needed, brush and then polish down with a cloth.
After each wear, put trees in them and give them a brush down.
Basically what I'd do if they were mine.
Oh, and look at the heals if they are worn/rounded quite a bit. Might want to have them replaced before too much wear to them. I've found local cobblers pretty inexpensive at this. Just pop in and ask to see some of their work to figure out if they might be right for you. Many love the v cleat and will have them done again. I'm either way on them and find that I tend to gravitate for shoes to wear out of the rotation that have rubber heals applied to them. Your preference. They are your shoes.
