Are there any wood experts here?

I was nosing round in the barn yesterday and found an old brass beer pump, which is mounted on a lovely piece of oak.
Well, I say lovely - it would be if I could figure out what to do with it.  It seems very dry and looks like it needs some attention.
I've got a few things here that I thought might 'moisturise (?)' it - boiled linseed oil, furniture cream etc, but if anybody knows of anything else, I'd love to hear. 
Also - is brasso the best thing for cleaning brass, or is there anything else I could use?

Thanks
Lisa

No to linseed & a big no to brasso

The best thing for wood is good quality beeswax(my cousin is a woodturner & very"into"the care of wood)& lots "elbow grease"

Brass I found this

> Tarnished Brass

>Unlacquered brass tarnishes when exposed to air. A weekly wiping with a little liquid ammonia on a soft cloth will help keep unlacquered brass shiny. .......................... On antique brass, test the cleaning product to be sure of obtaining the desired effect. Some methods not only clean tarnish but also remove the mellow coloring of age that is desirable on old drawer pulls and other accessories.

>To polish antique brass pieces, wash in hot, soapy water to remove grime, wax, etc. Rinse and dry. Moisten a soft cloth with boiled linseed oil and rub on the brass surface until all the dirt and grease have been removed. Polish with a soft cloth. Very old brass items, especially if in poor condition, require special care. Consult museum experts for advice. To polish for a soft finish: wash in hot, soapy water, rinse and dry. Make a paste of whiting and boiled linseed oil. Apply with a soft cloth and rub to remove tarnish. Wipe off excess paste and polish with a clean cloth. To remove heavy tarnish, difficult stains and corrosion: wash in hot, soapy water or a weak ammonia and water solution and rinse. Dampen a soft cloth in hot vinegar, then dip in table salt and rub the brass, or make a paste of flour, salt and vinegar. You may need several applications. When the item is clean, wash in hot, soapy water, rinse and dry thoroughly, then polish with a cloth moistened with lemon oil. If preferred, dip a slice of fresh lemon into table salt and rub over the corroded area. Wash, rinse and dry carefully.

That's brilliant.  Thank you Moonmaiden.
