There was a Power tool manufacturer called Bridges that used a similar cursive script to the Bridge mark on the plane...
Note later this firm became Stanley Bridges, part of the Stanley plane group (not sure if it was the US Plane & Level Co, or the UK firm - these tools were well known in the UK c 1950/1960...
Update, they were a UK based firm...
1961 Stanley Works (Great Britain) purchased all of the shares in the company from John Brown and others
Probably just a coincidence that they had a similar name and a similar cursive script logo
