OM70,

I can not find the information at the moment, so hopefully someone will be along.

I hope you can get ahold of him. The last time I spoke to the historian he mentioned he might be retiring soon.

A hint. Make sure you asked a bunch of questions (he likes to talk about the records) and note it all down. Browning has some odd rules about what they will put in the letter. As an example the original selling price will NOT be in the letter even if he tells you over the phone.
