Jeff Bozniac's book, "Mastering Rebreathers" has a fair bit on the history of different models. See if you can get hold of a copy of that.

i am looking for an expert in Draegers diving apperatuses(sp), particularily their oxygen models, predating the LAR V. i realize that still leaves alot of open territory, but that is about as specific as i want to be on an open forum.

contacting Draeger has been no help. they do not reply to emails. i had a buddy in Germany even try an email for me, and they didnt even reply to it as well. Draeger is no help at all in this matter.

what i really need is someone who knows the ins and outs of what was made, when it was made, what options or configurations it came in, etc.

thankyou for the help and suggestions so far,

Following an incident in which two people were injured when a gas cylinder valve ejected during analysis of a diving cylinder, the Health and Safety Executive have issued precautionary advice to anyone involved in such tasks, in order to reduce the risk of further acceidents.
A Draeger rebreather four litre steel cylinder had been charged with Nitrox and analysis was being carried out in the dive shop when the incident occurred.
Fitted to the cylinder was a charging adaptor supplied by the customer. The cylinder had no boot to allow the cylinder to stand erect, thus the person about to carry out the analysis had to hold the cylinder upright in one hand.
To allow the necessary low flow of gas release for the analysis, as the cylinder valve was being opened it created an unexpected increase in gas flow, which in turn caused a violent rotation of the cylinder.
The unexpected rotation of the cylinder injured the hand of the person holding it, resulting in the release of the cylinder from his grasp and causing the cylinder to spin out of control into the shop.
One customer in the shop tried to stop the cylinder from hitting his son by stopping it with his foot and in the process of doing so was also injured.
The valve, still fitted with the charging adaptor, was then ejected from the cylinder, causing the cylinder to continue uncontrollably out of the shop, travelling a further 20 metres before coming to rest outside the shop premises.
The valve, dislodged from the cylinder, travelled out of control for apporximately 3 metres inside the shop.
Analysis by scientific and engineering specialists has failed to provide a conclusive result as to why there was an increase in gas flow, or what caused the ejection of the cylinder valve.
The HSE, in order to reduce the risk of similar accidents occurring, have issued precautionary advice to anyone involved in gas cylinder analysis as follows:
"When a charging adaptor is fitted to the cylinder there is a possibility that if struck it will affect the torque applied betweeen the cylinder and cylinder valve. To reduce the probability of this happening charging adaptors should only be fitted immediately before charging and removed immediately afterwards.
Charging adaptors which are used with pure oxygen or enriched oxygen (oxygen greater that 21 per cent) gases should be suitable for use with oxygen. In order to maintain their 'Fit for oxygen' status when not in use they should be stored to maintain that status - for example, placed in a clean transparent bag which can be sealed closed and then placed in a second similar bag.
When carrying out any checks that require the cylinder valve to be opened the cylinder should be secured in a manner that allows both hands of the checker to be free. One hand to operate the valve and the other to hold any test equipment, and does not allow the cylinder to fall over or be dropped."

You might get some mileage contacting NRC - they seem to have a very good relationship with Draeger and provide the courses on their rebreathers. They were very helpful when I purchased mine and I spoke to a couple of people there who were very knowledgeable as regards older models (such as Atlantis and so-on) and will probably know the right people to speak to within Draeger for historical information.
