| Ru. 1069 Whyman has this job in hand, & the parts are nearly finished. These are four new pieces to be made in all, adapting the existing Humber Damper to the end of a B.40 Crank. Smedleys are doing the job which will cost about £3-0-0; a very cheap way of proving whether the remaining bit of vibration left in this engine is due to crank. CTS{C. Trot Salt - Carburation} | ||
