These shocks were on a 1973 dt-3 parts bike I bought at auction. Everything on the bike was painted black. Underneath the black on the shocks is orange making me think Boge/Muholands but there are schrader valves installed on these and the top ring that holds the spring is not split unlike any Boges I have ever seen. They are 14.25 in. eye to eye. Any help i.d.ing these would be much appeciated.
