Froggatt stamping question

I see these leg irons on ebay appear to be stamped "froggat" (I can't see the the second "T" on the provided photos). It seems odd that a workman could misspell the name of his company. Are there any other misspelt froggatt stampings known? A request to the seller for additional photos has not been answered.

Their is a second T stamped on the end, It is stamped lighter, but as an enlarged picture on my TV I can clearly see It.

It looks like a second T is barely visible at the end of Froggatt.

Trying to make a clean and even hand stamp on a flat surface can be a challenge,

stamp marking a rounded surface is even more difficult.
