That wouldn't bother me at all. I have 10 or 12 English and Belgium SxS Original's. and have made and or repaired sears and tumblers it just takes time and usually $20 or less in parts. Looking at rust on gun I would bet the lock needs removed and degreased and re lubed to repair. Worst case Dealer probably has parts and or a complete lock. That is a really good price I considered but I have 10ga ,12ga, 14ga now really don't want to start over again with supplies for a 20. LOL
