I've been on with this a while, and i dont know whether to swap it of sell it?

Basically,

I bought a new alloy piston head/washer/damper thing. (35 quids worth)
A new mainspring also.

Its a .177

it has the front sight, but the hood is missing.
I've got the rear sight, but the windage is missing.

The safety catch works, i never stripped the trigger unit down, but the rest of the pistol is stripped.
It needs a reblue or painting.
The gun is complete except from the sights.

This is NOT a for sale thread or a Swap thread!

I've always fancied a hw45 or a bsa lighting air rifle. So, what would you guys do? I'm really stuck, i cant afford the reblue at the moment.

Cheers
Andrew
