Jebber's suggestion is a good one.
I haven't found a way of searching the armed forces and consular returns on FindMyPast by page number but you can search by year (1945) and Location (Italy). It give 2,328 results. You could then trawl through looking for ones that just say Italy, not Venice or Bologna or wherever. That narrows things down. You'd be looking for page 1492, or possibly 1491 or 1493.
But let's try Jebber's suggestion first.
