<div>Michael- the 1260 is the early 32% OD. The 1292 is the 100 common 28% ratio. After that ODs for BN2s were 1308-28% and 1447-28%.</div>
<div> </div>
<div>I actually have an OD case #105 but 288 is a low serial number. Regards, Hank<br>

<div style="font-family:Aptos,Aptos_MSFontService,-apple-system,Roboto,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(33,33,33)">
I have 2 BN1 overdrives which I'm struggling to identify.</div>
<div style="font-family:Aptos,Aptos_MSFontService,-apple-system,Roboto,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(33,33,33)">
Unlike the later type "A" units the serial number on these is not prefixed with the ratio.</div>
<div style="font-family:Aptos,Aptos_MSFontService,-apple-system,Roboto,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(33,33,33)">
The serial numbers on these are :</div>
<div style="font-family:Aptos,Aptos_MSFontService,-apple-system,Roboto,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(33,33,33)">
1260/288</div>
<div style="font-family:Aptos,Aptos_MSFontService,-apple-system,Roboto,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(33,33,33)">
and</div>
<div style="font-family:Aptos,Aptos_MSFontService,-apple-system,Roboto,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(33,33,33)">
1292/2037</div>
<div style="font-family:Aptos,Aptos_MSFontService,-apple-system,Roboto,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(33,33,33)">
Anyone with information which would help identify the ratios of these?</div>
<div style="font-family:Aptos,Aptos_MSFontService,-apple-system,Roboto,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(33,33,33)">
Thanks.</div>
