I have 0C160. It's a Holland and Holland conversion but was never completed with the addition of a telescope. The Savage "T" conversions I've had, (both Mk.1 and Mk.1*), are all lacking the BSA selection "TR" on the left of the butt socket and finish "T" on the left side of the body. They've all had the S51 stamped on the underside of the buttstock providing the butt was still original and unchanged.

Remember too that H&H didn't put many of the well recognized markings on their conversions until 1943. You can find the examiner's marks and that's about it. I have a 1941 BSA/H&H that is "as issued" and has never been through FTR. It's devoid of the S51, TR and finish T stamps because it never had them to start with. The examiner's marks are all in the right places and it's right as rain.
