my norwegian-style spinning wheel is confusing me!

hi everyone! i've just come into possession of a spinning wheel and started to read up about how to use them. every tutorial i've read or watched has included the instructions, "thread the fiber through the orifice", the orifice being a hole through the bobbin or flyer.
the only problem is, my spinning wheel doesn't have an orifice at all! it doesn't have a hook to hold the thread with either. can anyone give me any advice on how to thread it so the yarn won't tangle in the flyer? i'd really appreciate it.

 

my kid is an expert...gimme a minute to phone her

 

nope, sleeping....i will answer this in the morning though...my daughter teaches old fashioned spinning and runs a wool business as well as demonstrations ...her house is straight out of ''little house on the prairie''

 

ok...my daughter said she suspects that you are missing a piece....can you take a photo?..
