Since downtube shifters are pretty much obsolete, their mounting bosses aren't being fitted to newer frames. Generally, smaller cable housing stops are now brazed/welded/glued to the headtube or very high on the downtube and many of these have barrel adjusters in them.
One side benefit of this is that the shift cable housing doesn't rub along the headtube and rattle against it and damage the paint.
One more thing the frame is drilled for old style brakes (nut fixing) I would like to fit modern brakes which i believe have a different fixing (allen key?)
This is a frequent request from riders modernizing an older frame and a search on this forum should turn up a lot of information.
Briefly, for the front brake you can enlarge the current 6 mm brake bolt hole in the rear face of the fork crown with a 5/16" (or 8 mm) drill bit and it will then accept the recessed nut used with newer brake designs. Drill out the REAR HOLE ONLY!
The rear brake is a little trickier as you can't easily drill out the forward side of the brake bridge as the seattube prevents access so there are a couple of options:
1. Buy two front brakes and use one in the rear. The longer mounting bolt will let you use an external nut like your current brakes.
2. Open up the forward-facing hole in the brake bridge by clamping a 5/16" or 8mm drill bit in a Vise-Grip and rotate the bit a fraction of a turn at a time to enlarge the existing 6 mm hole. This is slow and laborious but it does work. Then you can use a regular rear recessed nut brake.
Be sure you know what brake "reach" you need before buying. Older bikes often came with what are now called "long reach" calipers (47-57 mm measured from the center of the mounting hole to the center of the rim's brake track) while new bikes most often come set up for "short reach" brakes (37-47 mm)/
