25 pdr price question

[IronHat]

I noticed that the the cost of the british 25 pdr is about half of the US 105mm howitzer. For example a US field gun battery and a british howitzer battery both cost roughly the same but the US battery comes with 4 105mm while the British battery have 8 25 pdr.

I am wondering if this is intended or is it a bug due to I having patched the game from 1.0 to 4.5 after starting a long british campaign.
