Welcome to the forum
I have strong doubts on the imperial flag. Appears to be quite modern that has been aged.
But flags are not my expertise so others will be around with more knowledge
My greatest fear is that one day I will die and my wife will sell my guns for what I told her I paid for them

Welcome to the forum. The pennant looks like an original from what I can see.
