And as long as we're on the subject of WB wheels, while they have long been a mainstay of WWI modeling they are far from perfect. Below are a few of the things that are "not quite right" about the current (past?) WB wheels:

1. The inside wheel disk actually has "Wiliams Bros" molded into it and has no scale detailing whatsoever.
2. The tire has a very noticeable mold seam (which to be fair will probably wear off).
3. The spoke impressions (only 16 of them) radiate straight out from the hub to the rim (many WWI tires were not like this).
4. The molded in lacing on the "wheel covers" looks nice (particularly if carefully painted) but is not accurate for all aircraft.
5. The tires on the WB wheels are far too fat for earlier aircraft like the EIII.
6. The conical shape is a perfectly even rather than the slightly curved (volcanic?) look of the spokes in most old photos.

All in all the WB wheels are a quick and easy and reasonably good looking accessory for WWI models. However, for those who like to go "totally scale" these wheels are likely to be less scale than the rest of your model. And this assumed that you don't just open up the package and slap them on unpainted in totally stock condition. Many many WWI wheels covers had an inspection hole and duplicating this on the WB wheels would be challenging because the plastic is so thick. You have to carve out a much larger hole and then recreate the cover.

Don't get me wrong -- the WB wheels are a wondeful boon to WWI modeling but they aren't nearly as scale as the WB machine gun kits and probably less scale than a nice set of homemade wheels.
