I have a box full of these breakers, not sure how I aquirred them, and they have no identifying marks or labels. They resemble a GE Twin. THe only label is a UL Listing lablel. Can anyone help me identify brand and what panel they will fit?

Dear Mr. blaze777 (Electrical)

Che. 1. Sir, you are not sure how you acquired them, no identifying marking or labels, but only label is a UL listing.
This is probably? a [rejected item that failed the manufacturer's quality control]. This is why there is [no name of manufacturer , model and rating marking]. These rejected items are to be [destroyed] instead of allowing them to flow back into the market.
2. DO NOT attempt to use it all, irrespective of who was the irresponsible manufacturer/contractor who was responsible for the disposal! It is a potential time bomb. [Destroy] it and dispose of it. Prevent it from coming back into the market again. Thank you.

UL Listing label
 
There is another explanation. The matching panels are no longer made. A large number of breakers were left in stock at several levels of the supply chain.
Most of the old stock was eventually discarded. Some of the discards found their way into private ownership.
The challenge is not so much the quality of the breakers as it is the unavailability of matching breaker panels.
A breaker in perfect shape is worthless if you cannot obtain a panel that it will fit.

A lot of breakers don't have moulded on information. The older ITE breakers were like this and the current Cutler-Hammer breakers are. Once the sticker falls off, as it has in your picture, they're basically junk as you have lost the means to used to identify the breaker.

Thank you all for your replies, they are ITE/Challenger
 
In which case they should be disposed of. Back in the day, Challenger had a rather poor reputation. Particularly if you want your breakers to open under fault conditions.
