Gary Stephenson wroteMany thanks, that brochure picture is interesting with the asbestos inner door and the option of diagonal bolts. I was expecting a model type on the records like Patent for example, so it took me by surprise when it just had a number as an identifier. If I find anything else out I will let you know. Will try to PM patent.
Gary, some safemakers like Edw.Tann & Sons did not give their products names until near the turn of the Century. Rather their main lines were called simply No.1, No.2 etc. changing to List 2 List 3 etc around 1900, when names such as Excelsior, Household, Ledger came into use.
As far as I can establish Chubb safes in the 19th Century went by titles like Chubb New Patent or Chubb Fire Patent. Here are some old illustrations from my archive.

At the Great Exhibition of 1851 among many items they displayed their Banker’s Safe lock based on their Improved Patent of 1824 which secured the main boltwork either as illustrated or as part of a wheel lock for multi-bolt systems.
