Here is a fine English altar by Comper which I found on Facebook. The church is St Wilfrids, Cantley in Yorkshire. A comment says that the altar is still there but now has the big six on it. There is a hanging tester, but no hanging pyx (which is frankly rare in Anglican churches).
Anyway, here it is:
It is described as dating from 1894 and the photo would have been taken around that time.
Update. I have just received this photo of the church as it is now – beautiful. There’s a possibility the altar has been pushed forward for versus populum celebrations, but that is not obvious in the photo.
Up-update. Here’s another photo a kind soul sent to me via a link on his comment. It appears still to be eastward facing and like in the late nineteenth-century photo. Only the frontal and riddels are different, and there are no fewer than ten candlesticks on the altar – quite unnecessary – and shortened riddle post candles. Fortunately, in the Church of England, changes can’t be made to churches without a faculty, which is quite irksome to obtain, apparently. Perhaps the church is also a Grade I listed building. Thank goodness for such laws!
As a kind soul has reminded me, see my earlier article Four Riddel Posts Do Not Constitute the Sarum Rite.
