Thank you very much. I had spent some time already researching the callenge and found the dates of manufacture. The boker I know I had read a little about. And I know they are a common topic here. The bockla I couldn't find anything on nor the Toledo.
Do you think the boker is worth messing with? The blade looks to be worn pretty far. I'll get the good camera out and post better pics so perhaps you can give judgements on condition and value. Thank you once again.
