I was recently given a Browning Trombone .22. It seems to be in decent shape and I’m in the process of deep cleaning it. The serial number is in the low 37000s. It has a rear peep sight mounted on the stock that appears original or at least had been on the rifle for a long time. The aperture in the peep sight is very small, but there appears to be a second wider sight with a bigger aperture screwed into the side of sight. I don’t see much on line about this sight. Am curious if this is a unique model or possibly an aftermarket installation.
Thanks for any info you can provide.
