[Healeys] 100 Engine Numbers

[Perry]

Michael
Was looking at an on-line site regarding Austin Motor Co numbering/codes for engines and “H” was used in engine numbers but only to designate High compression engines.  L was used for low compression. It was not clear where in the engine number that H or L was placed. Never saw one. 
In that data base only three 100’s showed an H starting the engine number 224696, 229255 and 229217. If we could find the owners of these three cars they may be able to explain the reason for the “H”.

That's really weird Pat.
As I'm sure you know it was common practice to put an H in the engine number to indicate "High compression" but I've never encountered that with the 100.
Is there any pattern with respect to "Sold new in AUS"?

Thank you Bill
 
It remains a mystery. I have 623 BN1s and BN2s in Australia on my register and of these 71 have engine numbers starting with H1B.
 
There doesn’t appear to be any pattern and they are spread over BN1 and BN2s.

The engine in my 54 BN1 is a 1B******M
I have no idea if this is the original engine (It was about 10 years old when I bought it) but the car was registered here in NY using that engine number.

I have never seen an engine number H1B. Possibly somebody was supplying reconditioning engines but genine BMC engines were marked SRB-19 and then a short number
 
Best regards

Hello
 
The bulk of the engines fitted to the Austin-Healey 100 BN1 and BN2 start with 1B, but some start with the H1B.
 
Would anyone know?
 
Thanks
