I’ve been building models of many types all my life (I’m 70+ now) and i don‘t think I’ve ever built a “perfect” model.  I say: do the very best you can and don’t worry about some “error” that only you know about.  I believe that the main difference between a professional and an amateur is that an amateur will show you their model, but will then tell you it’s “ok” except for this or that feature.  A pro will keep his mouth shut!  
Also, even though you might try to be historically accurate, NO-ONE will know if something is amiss or not 100% accurate.  At the end of the day, you’re building a representative MODEL, not the actual ship or airplane or car or whatever!  
Build and enjoy!
