I think its a personal thing Colin. It comes down to what you have, or what you can get. and the skills we have. There are not so many carriers left around (there are mountains of them just a bit out of Adelaide) and we do what we can with what we have.
I love your threads. they show the original bits, and a professional way of repair, that we others can use as a reference.
Its time you did riveted carrier project to show us the way with them. The benefit to you is that you would then have a gem in your rock collection
Every thing I have seen from you is very professional, and this will be another professionally restored original carrier, that any carrier enthusiast would be proud to own
Keep the pics coming Colin
