Yes, I have this number in the excel file. It looks to be part of the post 65 shop numbering system where the first two digits are the year, 1967 in your case, then the last 3 digits would be the sequential frame number 117. I have heard of 125 frames per year so yours should be towards the end of 1967. However the numbers found would suggest that they went up to over 800 frames in 1969 and 1974. It could be that production rampped up in this period as I have not seen numbers this high in mid 60's. This is a well documented number series, but numbers identified so far are rather limited. Have you looked at the info on the link? bit too much to put in post.
