Inspired by this thread, I dragged out my MWF, which resides in an old TOBS cream container. I've plainly used as fair bit of it in the past, as what's there is a doughnut with a hole in the middle.
I wetted my Muhle synthetic (the one with more backbone), and laid into the soap as it is. With a good brushful of it, I then whipped it up in a shaving bowl, and shaved with my new OptionFive. There's plenty of lather, which does the job, but which lacks the body of many of the artisan soaps and croaps. I'd also forgotten how much of the distinctive lanolin smell it has; undisguised by any other scents.
Conclusions? It's a soap, it can be lathered as well as any other without difficulty, it enables a razor to get round the face smoothly, the lanolin gives me a bit of a skin-soothing finish, and a puck seems to last for ever. I'd say that, in the days before we were spoilt for choice, it was a good enough mid-range soap, between the West End luxury brands and the chemist's shop run-of-the-mill creams and soaps. It's a bit of a curiosity nowadays, and I wouldn't go out of my way to buy more of it, when there are many others that I like more; not counting the dozens I'd like to try, but likely never will.
