You wont find info because its not an original. Made up from 3 possibly 4 mowers.If it was purchased in 58 then it may have been a 2a but no 2a came with tin wheels nor that engine serial. Now its a bitsa. Engine in the image is model 5 Special code, not 2a. The base is std 70s utility with embossed victa rise base and incorect axle mounts. Engine is late as well,70 series. So its a mix of 3 or more mowers. Base on the 2a probably rusted out and this was used. Also for 58 it would have been the last of the 2a run as the 3 was already well into its run. If the original engine still exists that would be a plus as would the cowl and pulley. Otherwise its just messed up mix. Correct 2a coded engine will be large stamped 100,000 to 110,000 only.
