Just joined the site and looking for some advice

I bought an airpistol from a family friend about 12 years ago I guess. I'd never had a gun before but I was living in the country and fancied shooting some cans and targets out the back as we had no neighbours.

Anyway, it's an HW45 which I believe is a good pistol? I just loved the way it looked and felt in the hand, felt like quality! Anyway, it's been tucked away in the original box for about 11 years and I found it the other day and it re-kindled that desire to have a got at target shooting. So I'm thinking of visiting the local airgun club for a chat and to see what goes on.

Looking at the gun it still looks mint, and smells nice I haven't even shot half a tin of pellets through it since I've had it. Is there a way to work out how old the gun is?

Anyway, I need advice on cleaning, bearing in mind I'm new to this and never done anything with mine. What needs cleaning, lubricating etc... What do you use and where do you get it?

Appreciate any help
