This site has a lot of historical information on British Ericsson (ETL) Telephony equipment.  Most of the information relates to British Ericsson (ETL), but as L. M. Ericsson (Sweden) owned the company at the beginning of the last Century, then obviously their equipment is mentioned.

The part numbers changed over time.  Starting with three or four digit numbers originally, they changed to four digits with a two letter prefix around 1911. Then around 1926 the British company changed their part numbers to have four or five digits with the letter N as a prefix.

In general the British made models start with the prefix 'N', but they originally made and sold the Swedish telephones, so expect to find some with different part numbers.

The Ericsson pages are split into different sections - Telephones, Switchboards, PMBX and PABX.  A good place to start is the Ericsson main page.  But, if you do not know what precise product you want - then this may be the wrong route.

If you know the product section (i.e. telephone) and code number, then go to whatever product it is and search the list for the code number.

If you can only identify the product by a picture, then Quick Find should be helpful.  Go to the Quick Find section and choose the link that best describes your product.

If you only have a telephone circuit diagram number then go to the telephone lists and search for the diagram number (the diagram number does not relate to the product model number!).  Once found, this diagram number will cross reference to a model number, which will most probably be found in the product lists.  Please note that only diagrams prefixed by 'N' can be cross referenced.

Australian Ericsson's may be cross referenced in the Aus/NZ cross reference section.

Swedish Ericsson telephones normally have a an oblong number holder, either below the dial on table telephones or above on wall models.
