I've just been lucky enough to acquire a Shanks Thistle which doesn't seem that common. It dates from around the mid '30's and comes with a wooden sided grassbox with original transfer; there is also one on the chain case.
My immediate problem, particularly with the grassbox, is that I want to treat the surface rust without damaging the transfer. My thought is to carefully rub down around the transfer then apply Waxoil overall but I'm wondering if it might react with the transfer. Anyone got any ideas or experience of proposed treatment ?
