I had a similar wolf drill years ago, proper wrist breaker, I used to use it for drilling keelbolt holes on boats. Extremely well made.
however 50 or 60 years on from the production line there is a potential problem with all of them.
Metal case & dodgy wiring, Anyone who owns one of these would be wise to check the wiring inside, The flex & wiring from the switch etc used rubber insulation & it can & does go rock hard & become very fragile, in this state the machine becomes absolutely lethal & is liable to electrocute you.
