Hi Geoff,
Your helmet certainly sounds fine - as requested I've attached a couple of pics of mine. Interestingly mine was never issued, so has never been whitened. Internally its never been worn. Apologies for the rather poor quality of the photos, they were quickly taken in the kitchen!
I attach a pic of the rear two vent holes, I wouldn't put any great importance if your doesn't have these, they were possibly a manufacturing variation, perhaps on helmets supplied to the force shortly before the amalgamation, which could explain why this one never saw service.
Hi Jamie, thanks so much for the photo's, my mind is at ease! My helmet is essentially identical to yours aside from some subtle variances which could realistically be a result of either a different makers interpretation of the same specification, minor specification changes over time, or both. The differences are:
1. Mine has no rear vent holes.
2. Mine has a slightly narrower fabric band around the outside of it (about 20mm, same as the strap) whereas yours looks to be wider, possibly about 25mm?
3. The string threaded through the leather sweatband on mine is threaded through every 4th hole in the band, yours looks like it is threaded much closer. (If you look at post#142 on this page, Brian Wolfe posted a photo of the interior of his blue Velocette helmet,) my sweatband is 100% identical to that.
4. I can see some sort of stamp or mark on the sweatband of yours, mine has none.
On the subject of Brian's picture, you will also note that his still has all the cork lining right through the shell of the helmet, whereas yours & mine don't although mine has remains of it. Your helmet looks very nice & original Jamie, unfortunately mine has been re-blancoed at some point which partially obscures the "grain" of the fabric. Would it be fair to say then, that we both have a style of Brighton helmet which is even rarer than the already scarce "foot patrol" white helmets? Cheers, will upgrade my membership and post my pic's soon. By the way, I left Brighton as a 16 year old in 1971 and will be going back for the first time this year in October. I am hoping to go to the Police Museum in Brighton in my travels.
Cheers, Geoff.
