You may not have heard of Ten Point Nine
http://www.tenpointnine.com/ but I would recommend that you introduce your self to Phillipa , who runs the company. She not only adjusts off the peg clothing for shooters but will create garments at very resonable prices.
I heard of her via the grapevine and she comes well recommnended.
I will be visiting her in two weeks to have the sleeves of a jacket, I bought on an auction site , lengthened and the jacket adjusted. A top jacket that needs a tweak to suit me. From what I have heard Phillipa has enough experience to adjust jackets so they to work with the shooter , whatever their structural deficiencies, and I have many.
Today I saw her at the Lords Roberts Ctr, Bisley, with her display stand as the ESSU English Shooting Championships.
And in my eyes the fact that she is producing the jackets her self in the UK ( near Birmingham) an not in Europe or importing from the 3rd world means alot to me and if you or anyone else can support her business then that has to be good for British shooting.
Regards JJ.
PS I understand that the famous Tucker jackets, that used to be made in Surrey, are now manufactured in Asia.
