| APPENDIX PART 2. To compute the weight of Hn{F. C. Honeyman - Retail orders}'s Large Limousine body by Park Ward from the weights of the coachwork of 26-G-VI. Enclosed Limousine and 27-G-VI and 28-G-VI. Four door saloon and C.T.L. respectively. (1) F.D.S. 27-G-VI. = C.T.L. 28-G-VI + 5 therefore 9.8 in. doors = Division windows + 5 lbs. (2) F.D.S. 27-G-VI + 98 lbs = Enc.Lim. 26-G-VI. therefore 98 lbs = 8 in. doors + quarter window + extra seats + division - boot. (3) C.T.L. 28-G-VI + 103 lbs = Enc.Lim. 26-G-VI. therefore 103 lbs = 17.8 in. in body + extra seats - boot + quarter window. We know that 2 quarter windows = 15 lbs. 2 extra seats = 50 " 1 dropping division= 70 " therefore from (1) 9.8 in doors = 70 + 5 lbs. 1" in doors = 7.65 lbs. Then from (2) 98 = 61 +15 + 50 +70 - boot. boot = 98 lbs. Hn{F. C. Honeyman - Retail orders}'s proposed body equals 26-G-VI. plus the following 4" in body = 30.60 ) Extra weight = 128.6 lbs. Luggage Boot= 98 lbs) = 1cwt.0qrs. 16 lbs. Weight of 26-G-VI. = 11cwt.1qr.0.lbs. Additional weight = 1cwt.0qr.16 lbs. 12cwt.1qr.16 lbs. = Proposed Wraith III Limousine Say 12 1/2 cwts. | ||
