I have an old Bridgestone 400 in a smaller size and while it's a nice frame set other then for sentimental reasons I couldn't see putting a ton of money in it. The size of your frame is really what makes it special but straight guage chromolly frames are not uncommon on the used marketplace. Later Schwinn world sports would fit the bill. 86,87,88,89 I think we're all chromolly triangles and often available in large sizes.
