Would need pictures to properly assess the machine. It's mostly likely a later made #9 with the clip in bobbin. Earlier #9 had a different method to hold the bobbin in place. I do not know if you can get needles for it (it does not take a common size) and bobbins are only available vintage, and they are not cheap.
Attachments are also on the high end, so if it's got a bunch of bobbins and attachments, it may be worth it for them.
Paying someone else to get it running for you - IMO not worth it unless it has sentimental value to you.
