Loving your work John. I guess we're a bit lucky now with a mountain of new doors at Marks - but its cheating by just whacking a new door on rather than restoring the original like you're doing - plus I understand the US guys wanting to keep the original doors...All mine have export parts and that's what I'm use too!.
I'm very interested to see how you paint it to get the original WMS paint effects. I've seen the HEP jobs and they come out amazing - you could never pick it.
I also like your shed! Looks like its 100% purpose built for restoring pins!
