Vintage Soviet Lock with Missing Key - Restoration

In this video I'm restoring this beautifull Soviet padlock.
I found this lock for sale online and I really liked its design. It is made by "Metallist" probably in the 1960s. The lock came without a key, it was rusty and I didn't know what I was going to find inside once I open it. The case had some minor pittings due to rust, so I decided to use filler and paint it rather than sanding all the pittings down. The shackle is made of 4 plates and riveted together. I didn't like the looks of it so I decided to blend in every plate and give it a nice polish. Fortunately, the inside of the lock was in pretty good condition. The only thing that was worn a lot was the part where the key goes, so I decided to make a new one. The locking mechanism parts were in pretty good shape so I just smoothed the edges and blued them for protection. The trickiest part was making a new key. I looked online how the key was supposed to look, made some measurements and drawings and created a key accordingy. It really turned out better than expected and it works with the lock perfectly. I am happy with the end result of the padlock.
What do you think of this restoration? Feel free to leave a comment.
