I know someone who used to work for Liddy when he was with the Treasury Dept in the 1970's. He said Liddy used to F' with his bosses all the time, and he had a very close relationship with the Firearms Tech people at BATF, which had become a new agency. He was also involved with a lot of agencies that were doing classified weapons work as the Vietnam war wound down, so that is probably where the prototype, sterile CIA DEER Pistol came from - they (DEER Pistol) were designed and made right down the road in Alexandria, VA by American Machine and Foundry (AMF), the people who used to own Harley Davidson.
I used to play CYO Baseball with one of his neighbors' kids - but I never met him until the mid 1980's. The way he describes the neighborhood he lived in was very accurate.
There was a time when he needed money for some reason, and he let some of his handguns on consignment in a Maryland high end gun shop named Crawford International - for those of you who know Silver Springs, MD. I saw his Colt Detective Special and his Browning High Power pistol, but they were not in the showcase for long as I guess Liddy got funds from some other source and grabbed his weapons back. The owner of that store, Ken Crawford, did a lot of International Sales being so close to the Washington, DC embassies - and he had a huge stock of registered and legal Ingram M10 subguns with silencers in his store room. Image the scene from McQ when John Wayne test fired the Ingram - that was Crawfords! Well Crawfords had a B&W glossy picture of Liddy with a Ingram with silencer with his standing with some of the sales people. I am sure Liddy was glad no one saw that pic since he coule have been thrown back in prison for it. Crawfords closed in the early 1980's.
His .357 was supposed to have been handed down to his oldest son, who is a retired Navy SEAL. The other weapons were probably split up with the other kids since Liddy's wife passed awhile ago.
Definitely an interesting personality of that time frame. DC area was full of them - Walter Walsh with the FBI, Rex Davis with the BATF (former OSS), Col John Wood of Heckler & Koch (former OSS), and on and on.
Nice Smith Model 27 BTW!
