TOPIC: I guess now I'm seasoned.

I have no concern with the panel being old or being for fuses.  I do have a concern with double tapping, especially an Aluminum and a Copper together.  Considering the problems with maintaining tight connections with Aluminum, I wouldn't want to make matters worse by double tapping.  I pointed out to my client that the double tap on the fuse holder was a safety issue.  The double tap on the neutral bus is as well but to a lesser degree. The fact that the connection was loose does make me wonder though.  I have seen charred neutrals.  See the picture below.  The ground wire on the neutral bus is not that serious maybe but I have no idea why they would have done that.  Lots of room on the ground bus bar.

I agree Bert, failed to see that the wires were alluminum. Could not see the wire behind the double tap.
I do know that they make neutral bus bars with screws that are designed to take more than one neutral wire.

I have heard so many electricians tell me that a double tap on a neutral bar is not a problem, that I fail to believe anything anymore. I do agree on copper and allum. though.
I would still just recommend an electrician to repair anyways. I don't loose to much sleep trying to figure it out.
Let the experts fix it. Recognizing the defect is our job, fixing it is the licensed expert job .

Nice pics.
I can't find the right setting on my camera to take nice pictures like that.

After seeing the pics you made the right call.

This panel and wiring needs attention ASAP!!

That discoloration is very concerning. I think you client is entitled to a $250 refund.

Never come across alluminum wire, so looking at pictures always assume regular wiring.
I guess alluminum never made it up here.  ;D
Good job Bert.

I have not seen any solid conductor aluminum wiring in my area. But I do see multiple neutrals connected at a single lug and every once and awhile the discoloration like the ones pictured.

Here is a nice illustration.

Thanks Dave, good illustration. But why is it okay for alluminum and not for Copper. /
