Hi Mike
There was at George Hands who was the owner of the Stourport Tannery in Park Lane Stourport. He was dead by 1876. Information gleaned from the Access to Archives website
http://www.a2a.org.uk and the on-line directories
www.historicaldirectories.org.uk. I think that may well be your George Hands. Unfortunately there seems to be a gap for relevant directories on-line for Offmore Farm between 1855 and 1879. From that date until 1892 Robert Lloyd is listed as the farmer. He also ran the Lion Hotel in Kidderminster.
“Stourport-on-Severn - A history of the town and area” by Anne Bradford edited by Michael R Kettle, published in 2002 by Hunt End Books does not mention the Park Lane Tannery, but there is some information on tanning in Stourport that you may find helpful. There’s copy of the book at Worcestershire CRO, not certain if there’s one at the Worcester Family History Centre. You could search the on-line library catalogue for your area
http://opac.worcestershire.gov.uk/TalisPrism/index.htmla2a does list deposited documents from a Kidderminster solicitor re Hands and the Tannery and a search of the full index in Worcester may well give you more clues. You may find that the sale of Offmore Farm to Robert Lloyd may yield more useful info/plans.
I see that you would like a drawing or photo of the farm in the 1870's. Does that mean that you know the farm was subsequently rebuilt? If it wasn’t, then I guess that you have already looked - without any luck - at the pre-war aerial views of Kidderminster in the Worcestershire Photographic survey. Others maybe interested to know that Worcestershire County Council has over 60000 photographs taken in the county. The handlist can be found at
http://worcestershire.whub.org.uk/home/wcc-records-photo-survey-database Although Offmore doesn’t get a separate mention, the collection includes both pre-war and post-war aerial views of Kidderminster. The Offmore Farm Estate wasn’t built until the late 1960’s, but looking at the County Council GIS
http://gis.worcestershire.gov.uk/website/Environment/viewer.htm I am wondering if the farm still exists. The words Offmore Farm are shown to the east of the Offmore Farm Estate. I am not familiar with Kidderminster, so hope someone with local knowledge can help.
Commercial photographic companies had only been in existence for about 20 years in the 1870’s and I suggest that you email Ray Jones through his surfworcester photographic archive website for advice.
