Hello kafka bc!
Nice work! Some comments, suggestions:
- historically, the Clemsons emerged into the Towns by "kit bashing" -- which justifies your approach

- some of the RN and RCN Towns (including the Georgetown) were transferred to the SU in '44; consider to add them to the Russian roster
- SH3's 3inchSingle seems modelled after the 3"/45 20 cwt QF HA (= 12 pdr) but has no shield
- GWX came with nice skins for the Towns; to use them, you may set the model to accept external textures / multiple textures
- Ubisoft failed in modelling flushdeckers ...

- fitting splinter shields to objects is possible, some basic skills in 3D editing given. So, if privateer runs out of time, I could offer you some assistance, too.
