Hi Guys, thanks so much for your help! Sorry about having it upside

i have added a new pic the right way around.
It think it reads Rd 137188 not the '72' as suggested? i could be wrong of course.
I found it at a fleamarket, its was very inexpensive, it could see it the great work that had gone in to it and when I noticed the sig I thought 'im having you'
