I am not familiar with the Eduard set. If you could give me some more information I could maybe help out but part #s for this don't mean much to me. If you can do some basic scratch building, a little creative gizmology will produce something that will even fool some rivet counters. I've worked on them for 17 years and I will tell you that some things on a Hawk are just not worth the trouble to faithfully reproduce.
I will also be more than happy to provide some kit specific advice if you are not already familiar with those items which make the difference between a true L and an A+. Just be patient if you ask, I am only able to get on-line a couple of times a week and other things usually have to take priority so it will take about a week for a reply.
