Hi Mike, Your MM1 Class 22 kit’s coming along very nicely; I’m enjoying following the build. I agree regarding the side windows, which appear wider on the prototype. Still it’s a model and there’s always compromise regarding accuracy compared with the prototype. A Dapol Class 22 in 7mm is a nice thought, but I don’t think it will happen anytime soon. Hope I’m wrong as their OO gauge version’s very good, so a O gauge version would probably be even better. However, the MM1 kit looks good and hopefully your endeavours will encourage others to purchase one and have a go themselves. Best regards, Matt.
