The tyres of M1A1 155MM howizter

[Gunner]

Hi Kurtis:

Are you modelling a Canadian or US 155?

The Canadian ones were all M114A1 renamed C1. The key difference was the jack. On the older US models the jack was a huge geared square shaped post (see your photo). On the later models the jack was a circular tube about six inches in diameter.

Photographic evidence seems to indicate that the Canadian ones always were fitted with NDCC type tread.

Cheers! Mike
