Good used antique condition. May be a bit dusty from storage otherwise no obvious damage to the glass.
Metal clip-on style holder (approx 34mm x 37mm x 6mm excluding clip) has age-related patina/discolouration but still works OK.
2 square glass (approx 33mm x 33mm x 2mm including black paper border) yellow tone, 1 slightly lighter shade yellow than the other - could possibly be used together to make a darker filter.
1 oblong glass (approx 61mm x 33mm x 2mm including black paper border) graduated sky filter fades from yellow to clear - border loose/missing on 1 small section at clear end.
Probably date c1920s but may be earlier.
Provenance: belonged to a relative (passed down from previous generation).
Just having a clear out.
Can post at buyers expense.
