I have a small contention regarding SH and SHF as Samuel Hoppe. Samuel Hoppe is listed later in the 19th century and definitely as displaying a beehive mark.
Contrarily and confirmed in other threads, SHF is for Simon Helvig&Sons, SH as Simon Helvig.

The preponderance of 1820s and 1830s blades marked SHF without the beehive, to me, reads as the Helvig theory sticks. The French book not being the first, or last to have a differing opinion.
From Bezdek
"Samuel Hoppe & Sohn of Solingen was active between 1827-1861 (Bezdek:54) being Samuel Hoppe & Co. between 1861-1885 (Bezdek:54)"
So, that is not SH&F but rather clearly and in German, Sohn. The Feres or Fils and F of French notations Helvig. In my opinion anyway and I welcome more sources but as far back as my own studies go these past couple of decades, the Hoppe& Son(s?) and Co. marks are later than the Simon Helvig blades. A broad jump from the light b&g Helvig dress blades to the field infantry and cavalry swords known to Samuel Hoppe.
Cheers
