Ve are ver7 glad to have these photograph• for our 

historical records and I would have sent 7ou a personal 

note of acknowledgement long ago bad it not b$en tor 

the tact that I bad a recollection ot having come across 

something ver7 cloaelJ related to the subject vaen going through some old :f'iles. I bad put the thing ava7 and 

then could not reaember whers, but I knev it would 

tUl'n up eooner or later. The other daJ it did turn up and I am sending 7ou a photograph or the thing. 

This would appear to be the verr first model ot 

7our torm ot the strip cipher •7-stem. The strips themeel vea are about 1/8" v1de and 6• long. 'l'he7 ver• 

placed within tvo slots cut in a piece or cardboard 

·On vbich appears 1our name probabl7 written b7 70Ul'selt. 

When I ~e across this thing I made the note on the 

·thing vbibb 7ou ••• in -., bandn1 ting at the top ot the p~otograph. C&n 7ou now ••r1f7 ..., rema.rk1?
