(Sigh)–many thxx for reply; my DT/Hinkley list is a real mish-mash…
Made from old replacement parts catalogs, any two seldom agree if more than one listing, and they never seem to agree on the H/HA/HAA—
A 36 King Prod (I think they became McQuay-Norris?) lists DiamTs with Hinkley 200, 300, 400, 500, 700, 1400 and 1500 engines, all “HAA”, in the 20-25 period. A 1930 McCord omits most of those, but adds the “H1000” and “HA1600”. I’ve found these old catalogs to be not only incomplete but confusing and contradictory, and’ve gained a lot of understanding re’ parts counter people coming up with the “wrong” parts…
On the B-B2—that 36 King shows both a Hinkley B2 and a Cont’l B2 with 43/4 bore—there was a Cont’l B, but listed as a 2cyl in a 1917 ring catalog, and a 4cyl B2 43/4×6. Other catalogs show DT 5T with both the Cont’l L4 and B2. As I’ve found no Hinkley engines using just letter designation,. all being H-hundred number etc, I’m wondering if the Hinkley B/B2 is a misprint somewhere, recopied…
Again, my Hinkley list id incomplete, made from those same unreliable catalogs, So I could well be wrong…(again)…
