Video Gearheads please help!!!

I bought these two lenses at a thrift store and I would like to sell them on ebay. Problem is I don't know what models they are for or is the are universal, or even the thread size. If you know anything about them please help me out.

Thanks!

I do know that they are Tiffen, 1.5x tele, and wide angle lens atachments. There is a model number, I think thats what it is, C16946A on the bottom of the case, but I have not been able to use it to find any info.
