I purchased this as an original pen, original sticker a long time ago, and it has been displayed without being used at all. I don't think the foam has been shaved, and it fits quite deeply, around 58.5. The buttons are probably different from the usual r-t, the same as 500tx, so I think it's an early, early model? A transitional period model. It's an early r-t shell, so it's small. The sponge etc. should have been repaired, and you can wear it as is. The condition is very good, but it's over 50 years old, so please understand and judge based on the images and description. This is an item for collection and display. Please do not use it on public roads.
