"WEYMANN" VACUUM TANK.

X3593
X3579 [struck through]

We are sending to you a vacuum tank made by Weymann of Paris. This is the same make as is used on the "Delage". The "Weymann" appears to be a better made unit than the Autovac.

We are endeavouring to obtain some Weymann units which can be fitted into our tank which is being designed [word struck through, replaced with handwritten 'made']. we can then compare the "Weymann" with the Autovac.
