Stihl 038 chain brake

[openspaceman]

Could anyone familiar with these old Stihl saws have a look at this picture to see what they think may be wrong, the brake is held on because the distance shown by the red arrows is not far enough to cause the knuckle circled in blue to go over centre and hold the band off the clutch drum.

 

I cannot decide whether the front handle may be bent, the brake actuator handle wrong for the saw or the part circled in blue worn or defective.

 

I'm not very familiar with Stihls but have had 4 dropped off after they were retrieved from the workshop of a dealer who ceased trading. Not much else wrong with this one apart from a cracked rear handle, broken coarse thread screw stuck in the top AV and fuel filter clogged and carburetor full of fine dust.

Could just be the picture but there does seem to be a significant kink forward of the handle just above the top screw.

Yep I too thought the front (not brake) handle looked bent

Update

The handle was slightly bent but the owner had a couple more 038s and the chain brake handle is off a different saw, a bit of swapping around of front handles and the brakes both release, though the one I posted about has to have the brake handle back hard against the saw, flexing the AV to release.

Would anyone be able to work out dates  and cc from these stihl 038 serial numbers?
