Hi Warren, great images!
The sword (used1814-1905) and 2nd sword mark used 1906-1953. Standard mark for; small work silver minimum 833 fineness= 83.3% pure silver and used on small work without date letter and office mark and in combination with maker’s mark. Conjoined with the export key, mark to indicate 2/3 marking duty restitution upon export (used 1853-1953).
B&7 without cartouche not a maker’s mark but rather more an importers mark and unknown to me.
The maker’s mark, although de-formed, appears to be one of the maker’s mark used by; Hooijkaas Schoonhovensche Zilverfabriek; *HH* or *H.H+ or *HH+, in a rectangle with cut corners, used between around 1943-1953
