That's an added option. I missed out on the few 9.3x62 European trim 98 sporters that were imported, and subsequently tried to get one through a later group buy, but that fell thru with the importer. I ended up with a deal to import a non-US Sako 9.3x62 and gave up on the imported Mauser.
Good luck on your sale, but as noted above, with today's economy, it may prove difficult to find top dollar. IIRC, not too long ago a nice factory BRNO 98 sporter with great wood and the double-set triggers was on one of the auction sites starting at $1,300 and no one would touch it at that price. Not sure if it ever sold.
