I've been riding a '74 International for 40 years and have modified it to suit my requirements many times.
It's been road raced, used as a FG training bike, in cyclo cross, loaded touring and now as a town bike.
The Period Correct Police haven't issued any fines yet.

Service the bearings, install fresh rubber, re-gear as necessary and proceed.

The classic British clubrider's bikes were designed to be versatile, unlike so many one trick ponies today.
