found an air rifle under my shed. ..

Cheers for the help fellas.
I'm a bit clueless, though interested to pick up the hobby just luck and happenstance that I found it I guess.

The rust is only surface as far as I can tell, none in the breach, and only 1mm in the end muzzle.

Scope seems a bit much at 9x magnification what range would you expect from an air rifle?

I'll clean it up a bit and take it to a gunsmith for appraisal I guess? I'm in the uk.. should I dismantle it to travel? Or just wrap it up?
 
Cheers for all your help fellas.

I took it to a gunshop this morning and the guy there said it was a weirach but didn't know the model and that it was unserviceable, and beyond economic repair. He said the spring was stuck under tension and wouldn't fire. The barrel too rusted to salvage he said the stock was salavagable but wont look like it should. ..

So I get home a bit disappointed with it.. then I noticed a blob of rust on the safety stopping it from pushing in... scrapped it off and it pushed in with a nice click, aimed at nothing outside pulled the trigger and bang. A bit of dust come out. Went to cock again and it was bloody stiff so I think the spring hasn't shrunk like he said just that he didn't see the safety was on and wouldn't push in..

Advice on how to proceed?

Good stuff Harry, you're lucky that weihrauch uses loads of grease to grease the internals, and it probably will look better from the inside than the outside.
This is a very nice project gun, you have nothing to loose anyway.
I'd suggest to disassemble it, replace spring and piston seal, try to remove all the rust, coarse at first, and polish it afterwards. Cold (or hot if possible) blueing job to finish up.
I'm sure you will be amazed how this gun will turn out with some TLC:)
 
Wish I could find a weihrauch under my shed. Like others have said take it apart, clean it(well). Relube properly then worry about pellet size. But if you have to know right away( as I likely would) go buy a tin each of cheap .177 and.22 and push a couple down the barrel. It will be obvious which one works. better yet if you have a friend who shoots air rifles bring it over to his place. I'm sure he wouldn't mind letting you use a few pellets.
 
"Harry_Ola"Oh and I'd asked the guy about blueing it and he said it was around 3x the guns worth to re do it. I didn't think it was too costly material wise am I mistaken?
Cold blueing can give rather good results, but hot blueing is better.
I use "schnellbrunierung" from Ballistol Klever with good results:

When this isn't available in the US, Perma blue could also be a solution.

Make sure the metal is polished as good as possible before blueing. The smoother, the better. Also make sure the steel is completely free of grease before applying the blueing solution.
Brake cleaner works well for degreasing, and is cheap.
If I were you, I would try to do eveything myself, it isn't rocket science after all:)
