Sherpa 535L - sizing? U.K. made?

[Sherpa-Jay]

Hi

I am about to buy a Thorn Sherpa 535L
The frame has Reynolds 525 labels
The bottom bracket is stamped 535L03021

Can anyone please share the geometry sizes for this bike?
Do you know from the serial number what year it is?
Do you know where it was made?

I’ve tried the search function but nothing came up.
I’ve also tried the old back catalogue section and the brochure would not load.

Thanks 🙏

This http://web.archive.org/web/20090117093108/http://thorncycles.co.uk:80/thornpdf/ThornSherpaBroHiRes.pdf (the 2008 brochure) took a little while to load for me. I attach page 7 which shows the sizing. Page 5, however, refers to 969 tubes so perhaps your bike of interest is of a different generation but with the same geometry.
