I'm starting to get on with a restore of the PE 250 B I purchased from Gumtree a few months ago & the original air box is rooted . Does a RM air box of a similar year fit or does some one have one on a shelf or in a box in there shed they are willing to part with . It seems it a rare item to find , i'm a bit reluctant to make one from scratch .
