For the post drill collectors..have some ?s

Hey guys..havent posted in a good while. .My cat ht4 has not been on my priority list for some time but I do on occasion run my Hitachi ex120 hoe..Anyways have gotten to collecting old machine related stuff lately..old lunkenheimer oilers steam whistle valves, old cast iron hoist trolleys.etc..most of it I've been fortunate to be in the right place at right time.. My latest find has been a buffalo forge 611 post drill( somewhat incomplete)..Dont know a whole lot about them but do know that its missing the quill advance lever, the crank handle for the spindle gear and the base plate..Have located some buffalo forge parts off a 61R post drill. They look very similar to what im missing but they are a good distance away as an online purchase so its a shot in the dark without some good advice...any you guys familiar with the buffalo forge post drills of the past?..thanks Richard
