I bought my F-91W in 1997 - I know it's not a G but thought you might have some sxperience anyway. It's hardly been worn but has been round the world at the bottom of various bags over the years as a back up, and amazingly is still running fine on the original battery. Anyway - I'm trying to get a NATO strap on so I can wear it again, but it won't fit under the bars and the bars themselves don't seem to have springs in them as far as I can tell. The lugs are 'drilled' so to speak but I can't seem to shift the bars. Any tips for getting the new strap on? I've no plans to just buy a new one before anyone suggests it, I'm only bothering with this one as I'm curious to see how long it can remain functional.
