Ok ,Here's the lowdown . Better late than never .
I have an American ST Louis model A . My blade is 152mm wide 6" . 75mm deep 3" . 6.35 mm thick 1/4 inch.
My blade is straight cut at an angle of 17deg off 180deg . From tip to where the angle starts is 20mm.
I notice your machine has 2 screws on the blade mount plate which would correspond to 2 slots in your blade . My machine has only 1 slot . When i look a bit harder i see the ESTO has a slight outward curve to the handle while the American has a straight one .Apart from that all parts look interchangeable between the 2
Last week i got the urge to strip my machine down to bare bones and give it some love . Inspired by a youtube video i watched . ( video link below ) As of today it is down to bare metal and all the fittings mirror polished . My dilemma is what color should i paint it . Original color was black .When i got it 30 years ago it was painted ESTO green . Which frankly speaking has always been an eyesore . I am thinking powder coating it hammer-tone black with silver dimples or perhaps the bronze version .
BTW Doug61 . Who chose your color scheme ? Did you channel your inner liberace ? lol . It looks very "festive " for lack of a more appropriate word
