Chris, Meteor productions made an update set that included cockpit and correct main gear for the Wessex; I picked one up a few years ago before they went out of business. That does not help you much, but it does exsist, just a matter of finding one someone is willing to part with. Like finding the Holy Grail, huh? I'll dig mine out to see if there are any measurements in the instructions that may help out. Do you have the ability to make resin copies if someone supplies a master? Best Regards and good luck!
