I present to you two bayonets for the police with interesting markings. They were recovered with this frogs.
I hope that you will appreciate.
The first is a ACS with a starbust and which has the characteristic to have on the back of the blade a number that one finds on the frog stud : 418
The frog is stamped Otto Sindel Berlin 1929.
The second is a scarce model from Eickhorn of 30's, that I never saw since. There is the same number with two digits of the number on the finial. With the back one finds a starbust and the letter K.
