The various sources linked above contain lists of stakes and stumps. The stakes, at least, are identified with a number stamped on the shank of the tool. Not so with the stumps...measuring the OD and ID is the only sure way to know what you have.
But how sure is it? A quick comparison across the sources shows that many of the tools (stakes and stumps alike) experienced subtle changes in dimensions over the years. So it's possible to measure up a tool and find that it doesn't match the list you have...because the list is for a different time than the tool was made.
Some stake numbers appear to have simply been reused, providing us with another potential source of confusion.
I created a combined list of all the numbers, descriptions, and dimensions from all the sources above for both the stakes and the stumps. There is no easy way to make these large tables of data viewable as images, so I've made it available in two ways:

For those with access to Microsoft Excel here is a spreadsheet you can download:

For those without access to Excel, I've uploaded it to Google Drive as a Google Sheet. Anyone with a web browser can use Google Sheets to view and/or save the file. All you need is this link.
I hope having all of this information in one place will help avoid confusion for those attempting to identify their Inverto tools.
