Please help me identify this steering wheel - I think its from a Triumph

[jonsel]

I was clearing out my shed today and came across this steering wheel. I vaguely remember buying it many years ago for my Herald but never got round to fitting it. It's just over 15 inches in diameter.

Is it an original GT6 Mk 1 wheel or similar?

?

Looks like a Mk1, yes. Nice, too.

I think that the centre boss is too big to be a MK1 GT6 wheel.

It might be a 2.5PI steering wheel, or might be an after market wheel sold by Triumph.

check the splines - does it fit a spitIre/GT6 column, or as the hole bigger ?

if it fits the spit/GT6 column then it’s a Stanpart optional extra wheel, if not it’s a MK1 2.5PI Wheel.

 

[Colin Lindsay]

2.5 PI is certainly similar, and the one below does look to have a larger centre.

Thanks for your feedback.  Do you think if I measured the circumference of the boss it would confirm one way or the other? 

[KevinR]

It’s defiantly NOT an original GT6 MK1 wheel.  It’s either a MK1 2.5PI wheel or an optional extra stanpart wheel for a Spitfire or GT6.

the measurement you need to tell them apart is the diameter of the hole in the centre of the mounting boss.  The diameter of the steering column on the spit/GT6 is smaller than the one on the 2.5 PI

[jonsel]

It's 3/4 inch (1.9cm) diameter hole for steering column 

[KevinR]

Assuming you are talking about the diameter at the start of the taper on the bottom of the wheel it is a GT6/Spitfire optional extra wheel - the diameter of the SPLINED hole at the front of the wheel will be approximately 14mm.

If the diameter of the SPLINED hole at the front is 3/4" then it is likely to be a MK1 PI wheel.

The attached images are for a Stanpart Optional Extra wheel for a MK2 Spitfire.

Looks like a MK1 PI saloon wheel to me. Very nice thing to have though not much use to a GT6.......
