I got this little Stevens 87B about a year ago and it was extremely dirty. It would also jam with the locking bolt in the open mode as the detent ball and spring were missing. Finally got it fixed and really like this old gun. It has been soaked and sonic cleaned and and trigger and bolt polished. No scoring or marks anywhere and the springs replaced. Shot it some more Friday (Black Friday) and thinking may be more the "Click-Clack Sound of the action. Did find out that bolt will stay open until trigger released. Did need the locking bolt working as the will allow gun to function in semi-auto pushed in and single shot if pulled out. Just a lot of fun.When shooting it there is a slight delay from time shot fired to time the bolt actually starts moving to reload (may be just the click clack action deceiving). It does have some character and has been used but overall is very nice shooter. Glad is fully functional now.
