Looks Wakefield to me. Pretty sure it is for rubber power.
Definitely F1B props, from a while back. Walt Ghio of Sacramento who is known to NorCal flyers and is a world-renowned F1B flyer would certainly know about them and how to sell them. We have lots of FF guys on here, somebody may be interested directly. I fly only the smaller F1G so no use for these.
Acording to one of my FF gurus, it's for sure front ends and blades for F1B, consistent with Eastern European makes of 1995-2005 time frame. Unsure of value, though his best advise is to throw them on eBay. Hope that helps some.
