Some of the older Luxfer tanks had issues with microfractures or some such. Some dive shops refuse to fill them. Others do a modified visual and fill them. I don't know which numbers indicated a problem tank beyond Luxfer AL80 3000.
Ask a local shop if they'd fill it before paying for a hydro.

This was from the Luxfer site about the recall:
Between 1987 and 1988, Luxfer Gas Cylinders discontinued use of 6351 aluminum alloy and began using a proprietary version of 6061 aluminum alloy for all its aluminum cylinder models manufactured in the United States. Listed below are the dates by model number when the transitions to the new alloy occurred. Any current Luxfer models that do not appear on this list were never made from 6351 alloy in the first place and have always been made from Luxfer's proprietary 6061 alloy.

S808 - May1987
Based on the numbers in your post your tank looks to be fine. I would check with your local dive shop to see if they can service it.

FWIW, my old Luxfer, first hydroed in 1984, is one that has the issue. I don't think it was ever formally recalled.
I have had 3 Luxfer tanks that were part of the recall, found out when I took them for hydro and the LDS said don't bother because of the date. They said the hydro company wouldn't even touch them. It was off to the scrap yard after that.
