Hiya Jamie.
Like many have said here, the MRCE is a durable little bugger and for that reason I love it. It's damned near indestructible, which can be a good thing on some troops.
I also agree with many who have said that you will want to improve up to a movie accurate lid sooner or later. I'm ready to do that now, but I'll still keep the ol MRCE for troops that are likely to involve the public getting a bit 'too touchy'.
I don't know if its any help but there is a shop in Darlington ( Wow Factor ) that regularly stocks MRCE lids. Maybe if you found their E-mail they would post one out to you.
