Thank you, I had done a brief search on t'internet when I got the plane yesterday, I had found another example of Aaron Hildick' s blades, also a toothing blade by coincidence. I came across E. Preston but the Birmingham versus Sheffield locations were a good pointer to them not being related. I had not realised one was a maker and the other a dealer, so appreciate that information.
The problem with wooden planes is that I am finding it hard to stop them multiplying in my workshop, they are just really nice objects,and have character and history that my power tools, whilst very useful, just do not possess. Having said that I am quite fond of my little "free" Burgess bandsaw, which is as old as me but better looked after!
I will take some photos and post asap.
