Hi
The 1A6 was used in American Philco models 38 (Code 123) and, I believe, Model 39. Probably in others also, but these two are the first to come to my mind. It is a battery (direct-heated filament) version of the 6A7 pentagrid converter tube.
Your chassis layout is reminiscent of Models 38 and 39, save for the three-gang tuning condenser and extra coil shield can. So yours is, most likely, a variant of a 38 or 39, designed and built for the UK market. I would date it from between late 1933 through 1935. Certainly no later than 1935.
Many (if not most) of the Philco radio chassis in the mid-1930s were built in Philadelphia, with cabinets built at Perivale, Greenford, Middlesex. I believe the earlier Philco models (1930-32, possibly as late as 1934) were all built here (chassis and cabinets) and exported to the UK. Unfortunately, the schematics for all of the UK export models were sent over there, as far as I know, since most of the UK models differ to a greater or less degree from USA Philco models.
