I bought two last year, one about 9" and the other about 14" at an auction. The smaller has a cut blade, stamped Made in China, has the finest mouth of any I have seen, with a very well made brass insert. I'm still getting to grips with it but when I get it set up right, it takes a very fine shaving and leaves a very good finish.
The other came with a Stanley blade with a chip breaker which can't have been the original. No brass insert. I have had difficulty in getting it to work properly. A couple of days ago, I stuck in an uncut Herring blade, just to see what would happen, as it is the right width. The mouth is too narrow for bevel down, but bevel up, it is beginning to come together. I have no idea what the blade would have looked like, presumably something like the Chinese blade in the smaller plane, but a cut blade makes no sense. If anyone can post a picture of one of these planes with an original blade, I should be very grateful.
I will continue to play around with them to see how to get the best out of them, as I think they have great potential for the price. Be interested to hear how others get on. The smaller I push and pull, but the longer is more comfortable to pull.
