Yeah funny position of the numbers. Is that heavy grime on the front ring and Knox or marks from heavy use?

Here’s what looks like (?) an original Type B, molestered by some Neanderthal by rebarreling to 308 and altering the bolt handle. Either that or maybe a replacement bolt handle. Not quite sure what he means by short action - could it be a kurz? Or just an intermediate?
