Tell your Mum yes we do, my son tans them the old fashioned way, brain tanning, then we will be making them into period style stuff from the mountain man era. i love those old binos even though they are only about 3 power lol i use them with my black powder shooting gear. My favorite restore ever was a sunbeam mixer if i remember right it was the model 10. those old bullet looking ones with a ton of accessories. I have since given it to my daughter and she loves it. At almost 100 years those things will run forever and do anything a new one will.
