Small Scale Military Headquarters

Greetings,
Are the WWII Willy's Jeep & German Kubel. by 21st Century Toys truly 1/18 scale? I would like to purchase a few add-on parts for these vehicles.
Additionally would 1/16 accessories and weapons look out of place if used? I am not a rivet counter but I also don't want glaring / obvious differences.

yes they are truly 1/18 scale. 21st C was very good at keeping their vehicles true to scale. Sometimes the details on those vehicles were a bit over or under scale but the vehicles themselves were good, scale-wise.

1/16 accessories will probably look fine, if you are not a 'rivet counter'. . If you scrutinize, it will be obvious they are somewhat too large but 1/16 accessories will look fine to a casual observer. That said, 1/16 figures will be much more obviously too large...some collectors do use them, but it is more common to use 1/18 figures with 1/16 vehicles, than the other way around..

I appreciate the feedback, Ill keep it safe and purchase 1/18th scale add-ons for 21st Century vehicles.
-Regards
