When I bought my Healey in 1978, the Moss catalog was about 12-14 pages, IIRC (I found a copy on ebay a few years ago; it's around here somewhere...). I think they used that print version for a while, as I also remember a supplement catalog being issued (maybe it was an updated price list along with some pages of newly added parts...
Reproduction parts were just getting a foothold, as I remember Ray Caivano/Austin Healey West having quite a stock of new rubber bits, grill/trunk badges, splined hubs & other trinkets.
