Here the french equipment from 50s i draw from scaled blueprints:
https://photos.google.com/share/AF1QipP ... 1iZ0h6QWZ3
It is used in T47 DD's and E50,E52, E52b DE's.
Designation AT47 for torpedo tubes i found somewhere in these sites:

There were also some rare photos of K2 and L3 torpedoes.
The idea around this type 14 export version was that some countries may want some relatively cheap escort and ASW ships. Main target customers are smaller european, african and gulf countries. In real life, for example saudi frigate Al-Madinah have mix of french and italian weapons. Also 50-60's french government sells armaments almost to anyone who wants.
So i think about two variants - more advanced version i draw above, which can be sold to countries not too close with US and UK
and the second budget variant with US weaponry:
- mk33 dual 76mm mount replacing 57mm turret (only around 15 tons)
- Mk10 trainable Hedgehog instead 375mm ASWRL
- original project dual 533mm torpedo tubes, initially intended for Bidder torpedo, but instead using Mk35 U.S. ASW torpedoes, which started to being obsolete and US wanted to get rid of them at this time.
- pair of 20mm Oerlicons replacing 40mm Bofors
This modification can be freely sold to virtually any poor non-communist customer.
And this variant is very close to the gunboat You suggest.
About 76mm/70 Mk6 turret I thought about this variant, but it is very expensive and, more important, too heavy - 37 tons. I also considered Sweden 57mm turret, but i preferred french version to save weight (17 against 24 tons)
Yes, I also thought about SeaCat w/ M45 director or OTO Melara 76mm, but only as later upgrades.
