Dean look at the bus bar in the back up close, I think its deformed due to a poor connection or overload. Fitted Buckle its just a standard panel you can buy in Lowes or Home depot, the difference is these old panels use a old model of square D breaker which the main contacts of the breaker are like a saddle and the new breakers are a bayonet type and much cheaper. Just remove the old panel and replace with a new panel and use the new style breakers. Make sure you or whomever does this sizes the breaker with the wire size as over the years someone might have changed a breaker out to a larger one to resolve a problem and created a bigger one. Here is a picture of new and old style, new is on the left.

If your not electrically inclined do yourself a favor and hire someone who knows what they are doing, will save you money in the end and possibly your life.
