Well, sort of. To clarify a bit, UK TR4As were equipped with IRS, but American
spec 4As were available with either IRS
or solid axle (the S-T marketing thinking at the time was that US buyers would
be chary of the additional complications
of IRS). So, there are US market TR4As with both solid axle and IRS.
Cheers.
