I was lucky enough to get my hands on a Alan years ago. Great bike, not identical to the OP's but a really nice bike, none the less. I was impressed with the appearance as well as the ride quality. But one thing really bothered me. At 242 pounds, I thought that, perhaps, I was too heavy for the bike. Did some research and mention was made of how flexible the crank/bottom bracket were. I went for a ride to see for myself, My thoughts were that I was too heavy for the bike. The flexing at the bb was worrisome. But you have to admit, they are beautiful and something a bit unusual back then and, I suppose, now...
I helped a community group prepare these bikes, all sent by the Toronto police to Thunder Bay first nation community, to ensure they were in good working order and safe to ride. Managed to salvage between fifty and sixty bikes. I was given the Alan through the Thunder Bay Bicycles for Humanity "Earn A Bike Program". Wish I still had that wonderfully light (for its time) vintage road bike today.
My first glimpse of the Alan...
