Justus wroteI have several folding keys of this style but do not know much about them. Anyone have any info on where keys like this are from, age, anything else? Thanks!
Reminiscent of the old Ilco Steel Folding Blanks Nos. 1400-1402, see thumbnail attached from Catalog No. 7 Supplement dated 1/1/1926.
“Folding keys were invented for store door rim locks, indicating large rim locks were still much in use. With the folding key, unwieldy stem length could be reduced by one-half.”*
Your key is of cast construction and even older, likely nineteenth century.
