   A back bevel on a bevel up plane does not affect the angle of attack. I suspect the work you did just refined your edge to get you the improved results.

   The angle of attack on a bevel up plane is determined by the fixed frog angle and the bevel angle of the cutting edge.

   I've not heard of a #4 Marsh plane, but Google said it's a copy of a Stanley, that would be a bevel down plane. A back bevel has the same effect as increasing the frog angle. Rogfos is right it definitely helps with crazy grain. Sometimes I put a small back bevel with a 4000 grit stone and a strop. It only takes a short time. It does not need to be a large bevel. Like Rogfos I do not know the final angle I end up with.

   I have been collecting marsh planes for a few years now . I think the only one I am missing is the #8 . Not sure if they made a 5 1/4 . I have #2,3,4,5,5 1/2,4 1/2,6,and #7. They were made in Rockford Il.from 1915 to about 1924 then Stanley bought them out,just like they did with other companies. Marsh had what they called there rockford line that just had an R on the casting . I think Montgomery Wards sold some as there Lakeside planes . Marsh planes are almost like Stanley’s . The frog is machined on the sides along with the base for a nice tight fit side to side . I found the blades to be the same as Stanley on the #3,4,and5. I needed a replacement blade on my 5 1/2 and found it to be off 1/8 inch from Stanley that is for the slot in blades chip breaker for adjustment. I called Ron Hock and he made one for me .Also the 2 3/8 blades are like that too . I think the Marsh planes were made very well . I have a collection of Stanley also but I live in Rockford Il.so I thought I should collect the Marsh planes . I guess I got off the subject sorry .
