I noticed that credit was attributed to you for the early Auguste Francotte images of a double. Do you know if it was from the mid 1860s? There doesn't appear to be a serial number nor a patent number associated with the forend attachment, unless the T handle is really worn. I wonder who Auguste Francotte's frame source or frame filer might have been.

Did not the use of rebounding hammers commence circa 1867?

Kind Regards,
