Dear Sirs, SHOCK ABSORBER BELLOWS - F. {Mr Friese} 85395. As arranged when Mr. Leslie visited these Works on the 22nd of last month, we have now fixed the limits on the internal and external diameters of the 1½" bellows as follows:- Outside diameter 1.500" - .010". Inside 1.040" - .010". The last 26 units despatched to you have been fitted with bellows complying with this specification and we think that you will have no further trouble arising from variations in effective bellows area. We are enclosing Drg. No. BG. 775C showing this modification, and shall be obliged if you will have the internal diameter added to your own drawings. Would you be good enough to let us know whether you are likely to require any quantities of Shock Absorber Bellows fitted with 1¼" or 1.1/8" o {Mr Oldham} /d bellows in order that if necessary we may fix the limits on the inside diameters of these bellows. 26. 31.1.34 G1808 NOS 134729 TO 134768 | ||
