From my understanding there are a few different models of the Standard Rotary.
Maybe a picture would help. The pictures usually need to be reduced before you can post them.
Since it has a motor, it may have been 'modernized' at some point, but the mechanical workings and oiling should be the same.
The search on Quilting Board has been messed up for a while. It does work, but when you do the search (from upper right corner box of the page) you will get several results for "Standard rotary vintage" (without the quotes). When you click the link, it will fill in the page, but will not show the text of thread until you refresh the page. This can be done several different ways. I usually click the circle shaped arrow next to the address bar. Another way can be click on the blue title of the thread on the left side of the page, above the first post.
