"Building the WW1 Mark IV tank: size does matter." Topic

Follow the link to my blog and you'll see my dilemma. I have two nicely painted 25mm Foundry Mark IVs already on the tabletop. I wanted to add a couple more and decided to go with Old Glory, which from my previous experience with their No-Man's Land series, is a decent match for Foundry in terms of scale. However the OG tanks have turned out to be rather big to say the least. For the pics and details go to: diggershome.blogspot.com

Wow! From those pics its clear that ONE of those brands is way, way off from being 25mm (1/72) scale!

The Mark IV was 26' 5" which at scale would be about 4.4"

But that OG model looks like its nearly 6" long.

It is interesting to assume that Old Glory has it wrong. I know that the Old Glory tank matches in size with several other companies that make this same tank. And most work in 1/56 scale for 25mm and not 1/72 scale.

Consider figure size. Foundry figures are normally on the smaller side of 28mm. Whereas, other companies figures are more on the larger side of 28mm. I am sure that the person who make the tank for Old Glory also took into account the figure size when making the tank.

Plus, the person who make the tank for Old Glory, made models for the Smithsonian, which leads me to believe that he did do his research on the product.

I thought 1/72 equated to around 20mm figs, it's what I use for my Vietnam stuff. Therefore the OG is probably closer. Infact next to the figs it looks better, these were pretty hulking things.

I remember seeing a mark IV years ago as a youngster in the Imperial War Muesumn and thinking at the time how small it looked and how hellish it must have been to ride and fight in such cramped quarters!

I should have done this earlier. Measuring the two models in metric, here's the result. The Foundry Mark IV is 125mm long. The Old Glory Mark IV is 155mm long. Using Osprey's book on the Mark IV as my reference, the text for plate D states that the Mark IV was 8 meters in length (i.e. 8,000 mm). So, working from this, Foundry's tank is exactly 1/64 in scale, the equivalent of 25mm. Old Glory's version is in 1/52 scale, fairly close to 1/54 scale which is the equivalent of 28mm. Looks to me as if OG would go perfectly with such manufacturers as Great War.
