TX200 corrosion below stock line.

[p.j.]

Just bought a nice TX200, with almost new CS500 stock, all the visible bluing in very good condition.
On removing the stock there is a thin strip where the stock meets, where the finish looks like its rubbed of, and marked corrosion and loss of finish near the end of the cylinder, even the back block securing nut seems to have lost its finish. It seem like everything that has some contact with the stock has been affected in some way, makes me wonder if there is some thing in the stock oil. Perhaps a more plausible explanation is that it was put away wet in a previous stock, but its a strange presentation.
Im in two minds about returning it, but really all the visible parts are good, and has a WW kit, and Rowan trigger.
Anyone else with something similar?

There is something a miss, here, whether stock oil causing a reaction (?), damp being able to seep past the stock and puddle unseen, or just shoddy stock fitting when action is wet, either way, if it were me, it'd be on its way back for a full refund.

On close examination it has to be a chemical reaction to something on the stock, its not straight forward corrosion caused by damp. It looks like the bluing has been removed, and its all metal to wood contact points. You would never know unless you whipped the stock off.

I had a conversation recently with CS about oil for topping up the finish on a regular basis.
I was informed NOT to use Danish oil on the inletting, only the outside of the stock.
Maybe the previous owner wasn't aware of this and has oiled the inletting

I used Ballistol and ACF50 on an AA s400 and found that excessive use ie leaving it on, without wiping it down afterwards, actually thinned the bluing considerably.

Hi pj,
Hope all is well. Shame about the TX findings....

Although probably not related to your problem, I find the bluing weak or missing on the stock line of a lot of classics due to the rough finish of the internal of the stock, especially as the varnish solidifies the rough grain. I either use wire wool or fine sandpaper to take the roughness off. Surprising how rough the finish is when rubbing a finger on the internal stock.

All the best to all....
