findmypast have spent an absolute fortune in transcribing and advertising them and so it is very unlikely there will be in other online access sites anytime soon. I use the pay as you go option if i need anything from the 1911, it's ok on the find my past subscription you can access the 1911 inclusive of the subscription but it;'s 94.90 for 6 months or 149.90 for 12 months, but of course you get full access to everything else.
there's the pay as you go 280 credits for 24.95, that sounds alot but its 30 credits to look at the original return or 10 credits to look at the transcription, so thats 9 original returns or 28 transcriptions.
